Cinder volume services will perform cleanup on start, but when we have
multiple volume services grouped in a cluster, we may want to trigger
cleanup of services that are down.
This patch adds command `work-cleanup` to trigger server cleanups and
prints service nodes that will be cleaned and those that didn't have an
alternative service in the cluster to do the cleanup.
This command will only work on servers supporting API version 3.24 or
higher.
New command:
cinder work-cleanup [--cluster <cluster-name>] [--host <hostname>]
[--binary <binary>]
[--is-up <True|true|False|false>]
[--disabled <True|true|False|false>]
[--resource-id <resource-id>]
[--resource-type <Volume|Snapshot>]
