Pause and resume commands use HTTP POST instead of PUT

[56quarters]

Hi there,

First off, great project, thanks so much for creating it.

I noticed that pause and resume commands are using POST when talking to the Kafka Connect REST API instead of PUT

Specifically, these methods should be using PUT:

https://github.com/datamountaineer/kafka-connect-tools/blob/master/src/main/scala/com/datamountaineer/connect/tools/RestKafkaConnectApi.scala#L198

https://github.com/datamountaineer/kafka-connect-tools/blob/master/src/main/scala/com/datamountaineer/connect/tools/RestKafkaConnectApi.scala#L206

This is the result printed from the Connect Worker:

[2017-02-08 17:09:54,503] INFO 127.0.0.1 - - [08/Feb/2017:22:09:54 +0000] "POST /connectors/sqlserver-test-sink/pause HTTP/1.1" 405 323  2 (org.apache.kafka.connect.runtime.rest.RestServer:60)

Note the HTTP 405 response.

The API for these is specified here:

http://docs.confluent.io/3.1.2/connect/restapi.html#put--connectors-(string-name)-pause

I can submit a PR for these changes if you'd like. Thanks!

@56quarters Great, PRs welcome!

[andrewstevenson]

@56quarters Do you want to cover #20 aswell?

[56quarters]

I can submit a PR for this issue and I'll see what I can do for #20. I'll do them as separate commits / PRs if I make any progress on the latter.

I decided to only fix #21, not #20. I think #20 requires some judgement about the best way to do that and didn't feel like I could make that decision. Thanks!
