Pass a full instance to rotate_backups().

This patch renames rotate_backups() to _rotate_backups(), as this method
has never been used over rpc since it was first introduced in
75a87df739effe840e6cb39c976002e99b49c796.  The name change makes it more
clear that it's a private method.

The change also makes it so this method takes an instance dict instead
of just the instance_uuid as an argument.  This is mainly for
consistency with the rest of this file, where things are moving toward
passing the full instance dict around instead to avoid any potential
need for db access.

In passing, this also fixes up some uses of instance_uuid in
snapshot_instance() where instance_uuid is most likely None.

Part of blueprint no-db-messaging.
