Wildcard to indicate we want to mount unique devices during runner iteration

A bit of a hack
Updated commands to understand etcd.

build -> build
run -> run
stop -> stop
drop -> stop + remove entry in etcd
wipe -> remove all tags

To get the previous behavior of wipe you have to do drop first, then wipe.
