Open asynchronously a region or a set of regions on the region server. The opening is coordinated by ZooKeeper, and this method requires the znode to be created before being called. As a consequence, this method should be called only from the master.

Different manages states for the region are:

• region not opened: the region opening will start asynchronously.
• a close is already in progress: this is considered as an error.
• an open is already in progress: this new open request will be ignored. This is important because the Master can do multiple requests if it crashes.
• the region is already opened: this new open request will be ignored.

Bulk assign: If there are more than 1 region to open, it will be considered as a bulk assign. For a single region opening, errors are sent through a ServiceException. For bulk assign, errors are put in the response as FAILED_OPENING.

controller - the RPC controller
