Addresses for https://issues.apache.org/jira/browse/KAFKA-4878
* Adjusted the error message to explicitly state errors and their number
* Dried up the logic for generating the message between standalone and distributed
Example
messed up two config keys in the file source config:
````
namse=local-file-source
connector.class=FileStreamSource
tasks.max=1
fisle=test.txt
topic=connect-test
```
Produces:
```
[2017-03-22 08:57:11,896] ERROR Stopping after connector error (org.apache.kafka.connect.cli.ConnectStandalone:99)
java.util.concurrent.ExecutionException: org.apache.kafka.connect.runtime.rest.errors.BadRequestException: Connector configuration is invalid and contains the following 2 error(s):
Missing required configuration "file" which has no default value.
Missing required configuration "name" which has no default value.
You can also find the above list of errors at the endpoint `/{connectorType}/config/validate`

If leader node of one more more partitions in a consumer subscription are temporarily unavailable, request metadata refresh so that partitions skipped for assignment dont have to wait for metadata expiry before reassignment. Metadata refresh is also requested if a subscribe topic or assigned partition doesn't exist.

Closes#2406 from ijuma/kafka-4636-per-listener-security-settings
This behaviour was changed in 8b3c6c0, but it caused interceptor
test failures (which rely on callbacks) and since we’re so close to
code freeze, it’s better to be conservative.

Renames `HoistToStruct` SMT to `HoistField`.
Adds the following SMTs:
`ExtractField`
`MaskField`
`RegexRouter`
`ReplaceField`
`SetSchemaMetadata`
`ValueToKey`
Adds HTML doc generation and updates to `connect.html`.

Closes#2374 from shikhar/more-smt
Besides API and runtime changes, this PR also includes 2 data transformations (`InsertField`, `HoistToStruct`) and 1 routing transformation (`TimestampRouter`).
There is some gnarliness in `ConnectorConfig` / `ConfigDef` around creating, parsing and validating a dynamic `ConfigDef`.

Also:
* Make all implementations of `Time` thread-safe as they are accessed from multiple threads in some cases.
* Change default implementation of `MockTime` to use two separate variables for `nanoTime` and `currentTimeMillis` as they have different `origins`.

Kafka Connect REST API does not handle in many places connectors with slashes in their names because it expects PathParams, this PR intends to :
* Reject as bad requests API calls trying to create connectors with slashes in their names
* Add support for connector with slashes in their names in the DELETE part of the API to allow users to cleanup their connectors without dropping everything.
This PR adds as well the Unit Test needed for the creation part and was tested manually for the DELETE part.

Closes#2096 from ogirardot/fix/connectors-with-slashes-cannot-be-deleted
When storing a non-primitive type in a Connect offset, the following NullPointerException will occur:
```
07:18:23.702 [pool-3-thread-1] ERROR o.a.k.c.storage.OffsetStorageWriter - CRITICAL: Failed to serialize offset data, making it impossible to commit offsets under namespace tenant-db-bootstrap-source. This likely won't recover unless the unserializable partition or offset information is overwritten.
07:18:23.702 [pool-3-thread-1] ERROR o.a.k.c.storage.OffsetStorageWriter - Cause of serialization failure:
java.lang.NullPointerException: null
at org.apache.kafka.connect.storage.OffsetUtils.validateFormat(OffsetUtils.java:51)
at org.apache.kafka.connect.storage.OffsetStorageWriter.doFlush(OffsetStorageWriter.java:143)
at org.apache.kafka.connect.runtime.WorkerSourceTask.commitOffsets(WorkerSourceTask.java:319)
... snip ...
```
The attached patch fixes the specific case where OffsetUtils.validateFormat is attempting to provide a useful error message, but fails to because the schemaType method could return null.

Closes#2087 from mfenniak/fix-npr-with-clearer-error-message
There should be only one cases where these clean-ups have a functional impact: replaced repeated identical logs with a single log for the stale controller epoch case.
The rest should just make the code easier to read and make it a bit less wasteful. I did this exercise because unused variables sometimes mask bugs.
