Removing the nova-manage service subcommand is not a
feature, but it could impact upgrades, so this change
fixes the category of that change in the release notes.
Change-Id: I42def633f22353faf5e4df817b85a0f8b81a90f0
The novaclient already has the following service commands:
service-disable Disable the service.
service-enable Enable the service.
service-list Show a list of all running services.
host-describe Describe a specific host
This covers what the serivce subcommand of nova-manage provides.
Therefore the service subcommand was deprecated in 13.0 and now
it is removed.
