2c19b1c605 Fix online data migrations cmd in release notes
The online data migrations command in the release notes
needs to be corrected.

$ cinder-manage db online-data-migrations
usage: cinder-manage db [-h]
{online_data_migrations,purge,sync,version} ...
cinder-manage db: error: argument action: invalid choice:
'online-data-migrations' (choose from 'online_data_migrations',
                          'purge', 'sync', 'version')

"cinder-manage db online_data_migrations" is the right command.

423aa5c9a5 Fix names in online-data-migrations release note
Release note explaining ``cinder-manage db online-schema-migrations``
was created back in Newton, and was referring to wrong release names.
This commit fixes that by changing "Newton" to "Ocata" and "Ocata" to
"Pike".

942317aecd Add generic code for online data migrations
To limit downtime during upgrade we've decided to ban data migrations
done in migrations scripts and do them online during the runtime of the
cloud. This commit implements generic infrastructure for that.

This was part of a commit adding a mapping table between volume types
and consistency groups, but I've separated it because it's needed
independently. Also the aforementioned commit will probably be obsolete
when we finish generic volume groups efforts.
