This pull request targets https://issues.apache.org/jira/browse/KAFKA-6386
The minor fix to deprecate usage of `StreamsConfig` in favor of `java.util.Properties`.
I created separate public constructors using `Properties` in order to replace the old ones,
and prioritize new functions in the `KafkaStreams.java` file.
Since this is my first time doing open source contribution, I'm very happy to get
any comment or pointer to be more professional and get better next time, thank you Guozhang guozhangwang and Liquan Ishiihara!
testing strategy: existing unit test should be suffice to cover this change.

In dsi-api.html, when reading from Kafka to a KTable, the doc says "In the case of a KStream.." where `Kstream` here is not correct. They should be `KTable`.

This patch fixes a bug in the validation of the inter-broker protocol and the message format version. We should allow the configured message format api version to be greater than the inter-broker protocol api version as long as the actual message format versions are equal. For example, if the message format version is set to 1.0, it is fine for the inter-broker protocol version to be 0.11.0 because they both use message format v2.
I have added a unit test which checks compatibility for all combinations of the message format version and the inter-broker protocol version.

Add docs for the ReplicationBytesInPerSec and ReplicationBytesOutPerSec metrics. These metrics were introduced in KIP-153 (KAFKA-5194) but the docs were not updated.

**[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.

This PR implements the JIRA issue [KAFKA-4029: SSL support for Connect REST API](https://issues.apache.org/jira/browse/KAFKA-4029) / [KIP-208](https://cwiki.apache.org/confluence/display/KAFKA/KIP-208%3A+Add+SSL+support+to+Kafka+Connect+REST+interface).
Summary of the main changes:
- Jetty `HttpClient` is used as HTTP client instead of the one shipped with Java. That allows to keep the SSL configuration for Server and Client be in single place (both use the Jetty `SslContextFactory`). It also has much richer configuration than the JDK client (it is easier to configure things such as supported cipher suites etc.).
- The `RestServer` class has been broker into 3 parts. `RestServer` contains the server it self. `RestClient` contains the HTTP client used for forwarding requests etc. and `SSLUtils` contain some helper classes for configuring SSL. One of the reasons for this was Findbugs complaining about the class complexity.
- A new method `valuesWithPrefixAllOrNothing` has been added to `AbstractConfig` to make it easier to handle the situation that we want to use either only the prefixed SSL options or only the non-prefixed. But not mixed them.

With KIP-175 there are a number of consumer group command options that can be used to describe a consumer group.
This PR updates the documentation on consumer group command to mention those options.
This is the implementation of KIP-225.
It marks the previous metrics as deprecated in the documentation and adds new metrics using tags.
Testing verifies that both the new and the old metric report the same value.
