......................................................................
tool: new actions for adding and removing data directories
To add a data directory, a new FS root is created and within it, a new data
directory. Then, the set of all_uuids is updated to include the uuid of the
new data directory, and all of the on-disk instance files are updated with
the new value of all_uuids.
To remove a data directory, some sanity checks are performed, all_uuids is
updated to exclude the uuid of the data directory being removed, and all of
the on-disk instance files are updated with the new value of all_uuids.
Needless to say, removing a data directory will cause any tablet with data
in it to fail at the next startup.
