In this Jira we are planning to allow alter table command for a partitioned
table without specifying any partition name.
Proposed solution is to list all the partitions and find partitions that are
eligible to get compacted and put an entry for it in compaction queue

1. If you propose a new API, clarify the use case for a new API.

One of the problem could be ,let's say a table contains 1000s of partitions
and for some issue like files permission automatic compaction will mark all or
few partitions as failed and never pick for compaction.
After we see performance getting degraded, we find out that there is a
problem in compaction due to some issue.
Now to solve it, we have two approaches, adjust failure thresholds and
restart HMS to pick the changes which is not going to work for someone who
cannot restart HMS
And the second approach is to execute alter table mentioning each partition
1000+ times
