Description

Some ozone debug tools may require a consistent view into the RocksDB instance to function correctly and may give incorrect results if the DB is being used by a running OM. To fix this, we can have ozone debug operate on a RocksDB checkpoint if the Ozone process is running. This avoids users having to manually install RocksDB's ldb and make the checkpoint themselves. This could be an optional flag like --checkpoint that instructs the command to create a checkpoint from the RocksDB instance provided and read that instead.
