Description

In HBASE-25297 we intorduced the feature in hbck2 to fix orphan tables by generating the missing .tableinfo file. If the table descriptor can not be found in the tableinfo cache of the master, then hbck2 will generate a new file with default table configurations. In this case hbck2 could re-trigger a refresh of the in-memory table info cache of the master node.

We would need to add a new master RPC API to refresh the cache for a given table. Alternatively we should also test if a table disable / enable would do the same.
