Almost 100% null implementations, which is ok for most purposes
currently used by scylla. Some of these new calls (like dropped
mutations etc) should perhaps however be implemented.
Tested with the nodetool dtests. So sparsely.
Needed when/if scylla-tools-java is upgraded to origin 3.11,
otherwise noodtool breaks.
