Run FindCompactionTmpFiles utility via accumulo Admin

[ArbaazKhan1]

Added command option FindCompactionTmpFIles to admin commands.

closes issue #3986

Should there be a check to see if the system is up or if there running compactions? If this was run on a system with active compactions, would it find and delete files that were currently being written to be the compaction process?

As a stand-alone utility it is a little harder to run the command - if elevated to an admin utility, would that increase the chances that it would be run on an active system?

FindCompactionTmpFiles first finds the tmp files, then removes from that set any file that is referenced from currently executing compactions.

This looks good. I think you may want to add some tests to FindCompactionTmpFilesIT to test it using the Admin pathway. You can look at DumpConfigIT an an example on how to call Admin and pass the parameters.

May want to wait on merging this until after #4807 is merged, because I suspect there will be conflicts, or at least some related changes.

I remembered this was supposed to wait until #4807 was merged. #4807 has since been merged. I don't think tests have been added, maybe that needs to be addressed before this is merged

Any update on this? Think it just needs an IT
