Status of REST API in 0.10.x versions

[Spico Florin]

Hello!
  I would like to ask you what is the status of the REST API in 0.10.x
versions for the followings:
1. submitting a topology
2. killing a topology
3. listing a topology
I have read something about these features in
https://github.com/apache/storm/pull/464 and
https://issues.apache.org/jira/browse/STORM-615, but is not quite clear if
they are already provided or no.
If they are ready can you provide some examples on how to use them?
Thank you,
  Best regards,
  Florin
