cc_mounts: check if mount -a on no-change fstab path

Under some circumstances, cc_disk_setup may reformat volumes which
already appear in /etc/fstab (e.g. Azure ephemeral drive is reformatted
from NTFS to ext4 after service-heal). Normally, cc_mounts only calls
mount -a if it altered /etc/fstab. With this change cc_mounts will read
/proc/mounts and verify if configured mounts are already mounted and if
not raise flag to request a mount -a.  This handles the case where no
changes to fstab occur but a mount -a is required due to change in
underlying device which prevented the .mount unit from running until
after disk was reformatted.
