* KAFKA-9074: Correct Connect’s `Values.parseString` to properly parse a time and timestamp literal
Time and timestamp literal strings contain a `:` character, but the internal parser used in the `Values.parseString(String)` method tokenizes on the colon character to tokenize and parse map entries. The colon could be escaped, but then the backslash character used to escape the colon is not removed and the parser fails to match the literal as a time or timestamp value.
This fix corrects the parsing logic to properly parse timestamp and time literal strings whose colon characters are either escaped or unescaped. Additional unit tests were added to first verify the incorrect behavior and then to validate the correction.

Closes#6295 from ryannedolan/KIP-382
Implemented KIP-440 to allow Connect converters to use record headers when serializing or deserializing keys and values. This change is backward compatible in that the new methods default to calling the older existing methods, so existing Converter implementations need not be changed. This changes the WorkerSinkTask and WorkerSourceTask to use the new converter methods, but Connect's existing Converter implementations and the use of converters for internal topics are intentionally not modified. Added unit tests.

Added testing of logical types for Kafka Connect in support of KIP-145 features.
Added tests for Boolean, Time, Date and Timestamp, including the valid conversions.
The area of ISO8601 strings is a bit of a mess because the tokenizer is not compatible with
that format, and a subsequent JIRA will be needed to fix that.
A few small fixes as well as creating test cases, but they're clearly just corrections such as
using 0 to mean January (java.util.Calendar uses zero-based month numbers).

Closes#5225 from gunnarmorling/KAFKA-7058
KIP-305 added numeric converters to Connect, but these were added in Connect’s API module in the same package as the `StringConverter`. This commit moves them into the Runtime module and into the `converters` package where the `ByteArrayConverter` already lives. These numeric converters have not yet been included in a release, and so they can be moved without concern.
All of Connect’s converters must be referenced in worker / connector configurations and are therefore part of the API, but otherwise do not need to be in the “api” module as they do not need to be instantiated or directly used by extensions. This change makes them more similar to and aligned with the `ByteArrayConverter`.
It also gives us the opportunity to move them into the “api” module in the future (keeping the same package name), should we ever want or need to do so. However, if we were to start out with them in the “api” module, we would never be able to move them out into the “runtime” module, even if we kept the same package name. Therefore, moving them to “runtime” now gives us a bit more flexibility.
This PR moves the unit tests for the numeric converters accordingly, and updates the `PluginsUtil` and `PluginUtilsTest` as well.

Closes#5222 from rhauch/kafka-7056
This commit allows secrets in Connect configs to be externalized and replaced with variable references of the form `${provider:[path:]key}`, where the "path" is optional.
There are 2 main additions to `org.apache.kafka.common.config`: a `ConfigProvider` and a `ConfigTransformer`. The `ConfigProvider` is an interface that allows key-value pairs to be provided by an external source for a given "path". An a TTL can be associated with the key-value pairs returned from the path. The `ConfigTransformer` will use instances of `ConfigProvider` to replace variable references in a set of configuration values.
In the Connect framework, `ConfigProvider` classes can be specified in the worker config, and then variable references can be used in the connector config. In addition, the herder can be configured to restart connectors (or not) based on the TTL returned from a `ConfigProvider`. The main class that performs restarts and transformations is `WorkerConfigTransformer`.
Finally, a `configs()` method has been added to both `SourceTaskContext` and `SinkTaskContext`. This allows connectors to get configs with variables replaced by the latest values from instances of `ConfigProvider`.
Most of the other changes in the Connect framework are threading various objects through classes to enable the above functionality.

Reviewers: Randall Hauch <rhauch@gmail.com>, Jason Gustafson <jason@confluent.io>
The commits for KIP-145 (KAFKA-5142) changed how the Connect workers instantiate and configure the Converters, and also added the ability to do the same for the new HeaderConverters. However, the last few commits removed the default value for the `converter.type` property for Converters and HeaderConverters, and this broke how the internal converters were being created.
This change corrects the behavior so that the `converter.type` property is always set by the worker (or by the Plugins class), which means the existing Converter implementations will not have to do this. The built-in JsonConverter, ByteArrayConverter, and StringConverter also implement HeaderConverter which implements Configurable, but the Worker and Plugins methods do not yet use the `Configurable.configure(Map)` method and instead still use the `Converter.configure(Map,boolean)`.
Several tests were modified, and a new PluginsTest was added to verify the new behavior in Plugins for instantiating and configuring the Converter and HeaderConverter instances.

**[KIP-145](https://cwiki.apache.org/confluence/display/KAFKA/KIP-145+-+Expose+Record+Headers+in+Kafka+Connect) has been accepted, and this PR implements KIP-145 except without the SMTs.**
Changed the Connect API and runtime to support message headers as described in [KIP-145](https://cwiki.apache.org/confluence/display/KAFKA/KIP-145+-+Expose+Record+Headers+in+Kafka+Connect).
The new `Header` interface defines an immutable representation of a Kafka header (key-value pair) with support for the Connect value types and schemas. This interface provides methods for easily converting between many of the built-in primitive, structured, and logical data types.
The new `Headers` interface defines an ordered collection of headers and is used to track all headers associated with a `ConnectRecord` (and thus `SourceRecord` and `SinkRecord`). This does allow multiple headers with the same key. The `Headers` contains methods for adding, removing, finding, and modifying headers. Convenience methods allow connectors and transforms to easily use and modify the headers for a record.
A new `HeaderConverter` interface is also defined to enable the Connect runtime framework to be able to serialize and deserialize headers between the in-memory representation and Kafka’s byte[] representation. A new `SimpleHeaderConverter` implementation has been added, and this serializes to strings and deserializes by inferring the schemas (`Struct` header values are serialized without the schemas, so they can only be deserialized as `Map` instances without a schema.) The `StringConverter`, `JsonConverter`, and `ByteArrayConverter` have all been extended to also be `HeaderConverter` implementations. Each connector can be configured with a different header converter, although by default the `SimpleHeaderConverter` is used to serialize header values as strings without schemas.
Unit and integration tests are added for `ConnectHeader` and `ConnectHeaders`, the two implementation classes for headers. Additional test methods are added for the methods added to the `Converter` implementations. Finally, the `ConnectRecord` object is already used heavily, so only limited tests need to be added while quite a few of the existing tests already cover the changes.

Making clear that implementations of poll() shouldn't block indefinitely in order to allow the task instance to transition to PAUSED state.
Reviewers: Randall Hauch <rhauch@gmail.com>, Jason Gustafson <jason@confluent.io>
This changes the Struct's equals and hashCode method to use Arrays#deepEquals and Arrays#deepHashCode, respectively. This resolves a problem where two structs with values of type byte[] would not be considered equal even though the byte arrays' contents are equal. By using deepEquals, the byte arrays' contents are compared instead of ther identity.
Since this changes the behavior of the equals method for byte array values, the behavior of hashCode must change alongside it to ensure the methods still fulfill the general contract of "equal objects must have equal hashCodes".
Test rationale:
All existing unit tests for equals were untouched and continue to work. A new test method was added to verify the behavior of equals and hashCode for Struct instances that contain a byte array value. I verify the reflixivity and transitivity of equals as well as the fact that equal Structs have equal hashCodes
and not-equal structs do not have equal hashCodes.
