This caused a serious race condition, since the IPs managed by PVC had
not yet come up, but Zookeeper was trying to start and bind to them,
which of course failed.
Remove these dependencies entirely - the daemon itself starts these
services during initialization and they do not need to be started by
systemd first.
Rename "pvcd" to "pvcnoded", and "pvc-api" to "pvcapid" so names for the
daemons are fully consistent. Update the names of the configuration
files as well to match this new formatting.
