15.0.0: Start of Pike development and Ocata Release support
This tag signifies the start of Pike development and the release of
Ocata. Starting with this tag Tempest officially supports the
following releases:
* Mitaka
* Newton
* Ocata
The release under current development as of this tag is Pike,
meaning that every Tempest commit is also tested against master during
the Pike cycle. However, this does not necessarily mean that using
Tempest as of this tag will work against a Pike (or future release)
cloud.
NOTE: Usually Tempest for a new development was tagged after final
release of the previous development. However, this tag is pushed
before the final release because we need a new tag before the
first PTG which happens before the final relase.
