> After HBASE-12859, we can now track the last major compaction timestamp for each region.  However, this is only exposed through cluster status reporting and the admin API.
> We have similar per-region metrics around storefile age, but none that filters on major compaction specifically.
> Let's add a metric for last major compaction age.
