Most of these operations can be accomplished using the REST API [1],
with the 'quota_usage_refresh' command being the sole exception. This
particular command is duplicated in a new category - quota - thus
allowing us to fully deprecate the entire 'project' and 'account'
categories.
Note that the '(project|account) quota_usage_refresh' command has been
named 'quota refresh' and not 'quota usage_refresh'. This is because
cliff, which will be used by 'nova-manage' in the future, does not
support underscores in command names.
