> There's been a few occasions where different customers had faced the need to reduce the
number of regions for specific tables, either due to mistakenly pre-split or after a purge
in table data. This jira is for adding a simple merge tool that takes the table name and the
desired number of regions, then perform region merges until the total number of regions for
the given table reached the passed valued.
