Problem Description:
Hot tier brick gets 100% full even when cluster.watermark-hi has been set to
90.

Analysis:
When IO is started on tiered volumes, there is no test to check if the usage of
the brick has breached the hi-watermark. This causes the file to continue to
grow beyond the hi-watermark and eventually consume the entire brick space if
the IO continues without any checks.
