MT#11263 Start/stop glusterfs-server manually for manipulations with network.yml

We have migrated to ngcp.inc with modern list of services to be stopped
at the end of ngcp-installer.
See commit e75b01441c for more details.

Unfortunately deployment.sh is performing 'magic' with network.yml and depends on glusterfs
for pulling/pushing configs from/to shared storage. I am planning to move this 'magic' to
ngcp-installer, but while it is here, we have to start stop glusterfs-server manually.
