Add proto definitions for MarkUnverified RPC

With the introduction of metadata verification, Praefect needs a tool
to manually mark a repository as needing verification immediately rather
than after the specified verification interval has passed. That tool will
require a new RPC that it can call achieve its goal. This commit adds the
proto definitions for MarkUnverified RPC which can be called to either
mark a single repository by ID, a whole virtual storage, or a whole storage
as needing verification.
