Subject: [PATCH] Install required packages for NFS/CephFS mounts

Currently it's deployer resposibility to install required binaries for
mounts to succeed, which is not really convenient. Instead of this
we can try to provide at least some basic binaries installation in case
supported type is set.

Depends-On: https://review.opendev.org/755484
