Code Issues Proposed changes

Add APIv2 support to make host optional on evacuate

Browse Source 
In the event of an unrecoverable hardware failure, support needs to
relocate an instance to another compute so it can be rebuilt.

The changes involved in this patch are:
  [*] Add a new v2 extension to determine that the host argument
      on evacuate is now optional.(Extended_evacuate_find_host)
  [*] Doc regeneration.

DocImpact: The evacuate target host is now optional.
If 'host' field is not sent in the request, the scheduler will
determine the target host.
This will include nova client changes ( on the proper commit ) to support
this new optional parameter.

Implements: blueprint find-host-and-evacuate-instance
