KUDU-3340 [compaction] Disable compaction on the specified table

For tables with only inserts but no updates, we can disable the
compaction of the table's data, which can improve the search
efficiency (the effect is more obvious in the search scenario
involving multiple tables).

> Background:
>         In actual use, we found that some tables only have inserts and will not be updated forever, with only a few queries and will be migrated to HDFS in a short time. Compact has no actual benefits for such tables. On the contrary, when a query involving such a table is scheduled for compact, the query time will be increased. Therefore, we need to add configuration and disable compact for the specified table if necessary.
