Subject: Microversion 2.73: Support adding the reason behind a server lock

This patch adds a new parameter ``--reason`` to ``openstack server lock``
command and ``--locked``, ``unlocked`` filtering parameters to
``openstack server list`` command. This can help users to provide a
reason when locking the server and to filter instances based on their
locked value from 2.73 microversion.

Implements blueprint add-locked-reason
Depends-On: https://review.opendev.org/#/c/661785/
