cluster/tier: add pause tier for snapshots
This is a backport of 12304
Snaps of tiered volumes cannot handle files undergoing migration.
We implement a helper mechanism to "pause" migration. Any files
undergoing migration are aborted. Clean up is done to remove
sticky bits and data at the destination. Migration is restarted
after snap completes.
For testing an internal switch is added. It is not exposed externally.
gluster volume set vol1 tier-pause [true|false]
