Description

It would be useful to have a tool that could mark a tablet as "quarantined" or manually "deleted", so that the TSTabletManager does not attempt to start the tablet. This would be helpful in the case that there is a problem with the tablet that is causing a TS crash on startup, for example.

Quarantining could carry out the following steps:

1. Construct a tar ball consisting of the contents of the tablet, including superblock, data blocks, write ahead logs, consensus metadata, and any other relevant information. This could be saved for later debugging by a Kudu developer.
2. Safely remove all of the contents of the tablet, including all data blocks.
