Plugin API for change and revision

Change [1] started to implement new API with RevisionApi.review.
This change implements the following API methods:

* abandon
* rebase
* restore
* revert
* submit
* delete (draft)

SSH review command was migrated to utilize the new API.
Acceptance tests were added for the new API methods.
