Hold minor compactions when tablets files exceed pause limit

**Is your feature request related to a problem? Please describe.**

As part of the work on #5023 and #5104 a new property `table.file.pause` was added that causes bulk imports to pause when a tablets number of files exceeds this limit. Pausing was not implemented for minor compactions.

**Describe the solution you'd like**

When a tablets files exceeds the pause limit minor compactions will be held on the tablet server. This should cause back pressure for live writes when compactions are not keeping up.
