I don't think these concerns warrant a revert. The attached patch-set
moves the code (not the doc) to ctdb/utils/etcd, and adds a new
--enable-etcd-reclock configure switch. Would this be sufficient?

I'd prefer to keep the man page under doc/. We could change the
makefiles to only generate/install if --enable-etcd-reclock is flagged.
