(core) add endpoints for clearing snapshots and actions

Browse Source 
Summary:
This adds a snapshots/remove and states/remove endpoint, primarily
for maintenance work rather than for the end user.  If some secret
gets into document history, it is useful to be able to purge it
in an orderly way.

Test Plan: added tests
