This PR allows setting a "hard" or "fifo" quota restriction at the bucket level. Buckets that have reached the FIFO quota configured, will automatically be cleaned up in FIFO manner until bucket usage drops to configured quota. If a bucket is configured with a "hard" quota ceiling, all further writes are disallowed.
