cluster/tier: allow db queries to be interruptable
A query to the database may take a long time if the database
has many entries. The tier daemon also sends IPC calls to the
bricks which can run slowly, espcially in RHEL6. While it is
possible to track down each such instance, the snapshot
feature should not be affected by database operations. It requires
no migration be underway. Therefore it is okay to pause tiering
at any time except when DHT is moving a file. This fix implements
this strategy by monitoring when control passes to DHT to
migrate a file using the GF_XATTR_FILE_MIGRATE_KEY trigger. If it
is not, the pause operation is successful.
