Michał Dulko 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".

upgrade:
- To get rid of long running DB data migrations that must be run offline,
Cinder will now be able to execute them online, on a live cloud. Before
upgrading from Ocata to Pike, operator needs to perform all the Newton
data migrations. To achieve that he needs to perform `cinder-manage db
online-data-migrations` until there are no records to be updated. To limit
DB performance impact migrations can be performed in chunks limited by
`--max_number` option. If your intent is to upgrade Cinder in a non-live
manner, you can use `--ignore_state` option safely. Please note that
finishing all the Newton data migrations will be enforced by the first
schema migration in Pike, so you won't be able to upgrade to Pike without
that.
