Add GPFS5 bind mounts to NHC configuration

We are bind mounting several GPFS5 directories for backward compatibility (see /usr/local/bin/mount-gpfs-bind-mounts.sh script below, which is called by /etc/systemd/system/rc-gpfs-bind-mnt-dirs.service)

/home -> /gpfs/user/home
/data/user -> /gpfs/user
/data/project -> /gpfs/project
/scratch -> /gpfs/scratch
/share/apps -> /gpfs/project/clusterops/rc-apps/intel-el7

We discovered several nodes that had just recently been added to the GPFS5 pool that had booted without the bind mounts. SSH'ing to the nodes and running systemctl restart rc-gpfs-bind-mnt-dirs.service successfully created the bind mounts.

As such, we need for NHC to monitor for these mounts. Proposal is to add the following checks:

# GPFS5 clients - GPFS5 and bind mounts
## /gpfs
   {c0[194-223],c0[252-253],c0255} || check_fs_mount_rw -t gpfs -f /gpfs
   {c0[194-223],c0[252-253],c0255} || check_file_test -r -e -f /gpfs/.nhc-test
## /scratch
   {c0[194-223],c0[252-253],c0255} || check_fs_mount_rw -t gpfs -f /scratch
   {c0[194-223],c0[252-253],c0255} || check_file_test -r -e -f /scratch/.nhc-test
## /home
   {c0[194-223],c0[252-253],c0255} || check_fs_mount_rw -t gpfs -f /home
## /data/user
   {c0[194-223],c0[252-253],c0255} || check_fs_mount_rw -t gpfs -f /data/user
## /data/project
   {c0[194-223],c0[252-253],c0255} || check_fs_mount_rw -t gpfs -f /data/project
## /share/apps
   {c0[194-223],c0[252-253],c0255} || check_fs_mount_rw -t gpfs -f /share/apps
