Description

CUrrently there is no nodetool command to validate all sstables on disk. The only way to do this is to run a repair and see if it succeeds. But we cannot repair the system keyspace.
Also we can run upgrade sstables but that re writes all the sstables.
This command should check the hash of all sstables and return whether all data is readable all not. This should NOT care about consistency.
The compressed sstables do not have hash so not sure how it will work there.
