Bugs fixed

• reworked race condition fix included in the last release. using consistent reads in fleetd for etcd was deemed too demanding, but watches don't work as expected against etcd 0.4.x. instead we wait for unit creation in fleetctl before proceeding with other actions.

Known bugs

• does not correctly wait for unit creation when the unit exists on the local disk but not in the remote registry. this is fixed in release v0.11.4.
