Create method to remove defunct MaaS alarms

[Matt Thompson]

https://github.com/stackforge/os-ansible-deployment/commit/f620e31440bf00b8813d43e76d6df534eacbf44d and https://github.com/rcbops/rpc-maas/commit/b05d0d1b98171c5594cde735d4921b86bb86d35d change metric names for galera and rabbitmq. We need a method to remove the old alarms so that they do not misfire once the above code is deployed.

    Add functionality to nuke old checks and alarms

    This commit adds some basic functionality to rpc_maas_tool.py to nuke
    old alarms that should no longer exist. These include alarms containing:

    WSREP_CLUSTER_SIZE
    WSREP_LOCAL_STATE_COMMENT
    disk_free_alarm
    mem_alarm

    We limit deletion against alarms that also include
    rabbit_mq_container or galera_container.

    We also delete any checks that were created without filesystem patch
    included. Note that remove-defunct-checks should not be run against
    an icehouse installation as the change to check name was not backported
    there.

    Closes-Bug: #1416476
    Change-Id: I3528f5712d5a2d6a15e718516f0dab9ea2c68c27
