Added test to check mounted file systems on control plane VMs

Problem: sometimes it happens that after KVM host is rebooted,
its VMs come up with missing mounts (e.g. ctl node can have
keystone volumes missed). We had such an issue. It can happen
because of the hardware / host system performance issue or
network misconfiguration, but such issue can appear after
e.g. HA testing, or when KVM is rebooted. So, such test
will detect the inconsistent mounts.

Created the test to check that mounted file systems are
consistent on the virtual control plane nodes (e.g. on ctl,
prx, etc nodes). The nodes like kvm, cmp, ceph OSD, nodes
with docker (like k8s nodes, cid, mon) are skipped.

To skip other nodes if needed, add the node or group in the
config (skipped_nodes, skipped_groups).
