Description

Occasionally we've hit cases where a tablet is corrupt in such a way that the tserver fails to start or crashes soon after starting. Typically we'd prefer the tablet just get marked FAILED but in the worst case it causes the whole tserver to fail.

For these cases we should add a 'local_replica' subtool to fully remove a local tablet. Related, it might be useful to have a 'local_replica archive' which would create a tarball from the data in this tablet for later examination by developers.
