pcs resource manage --monitor enables the monitor operations for all resources in a group in a Pacemaker cluster

Issue

• I had two resources in a group unmanaged with their monitor operations disabled. I ran pcs resource manage --monitor on one of them. But this enabled the monitor operations for both resources.

# pcs resource show dummygrp | egrep '(Group|Resource):'
 Group: dummygrp
  Resource: dummy1 (class=ocf provider=heartbeat type=Dummy)
  Resource: dummy2 (class=ocf provider=heartbeat type=Dummy)

# pcs resource unmanage --monitor dummy1 && pcs resource unmanage --monitor dummy2

# pcs resource config dummy1 dummy2 | egrep 'Resource:|Meta|monitor'
 Resource: dummy1 (class=ocf provider=heartbeat type=Dummy)
  Meta Attrs: is-managed=false
              monitor enabled=false interval=10s timeout=20s (dummy1-monitor-interval-10s)
 Resource: dummy2 (class=ocf provider=heartbeat type=Dummy)
  Meta Attrs: is-managed=false
              monitor enabled=false interval=10s timeout=20s (dummy2-monitor-interval-10s)

# pcs resource manage --monitor dummy1

# pcs resource config dummy1 dummy2 | egrep 'Resource:|Meta|monitor'
 Resource: dummy1 (class=ocf provider=heartbeat type=Dummy)
              monitor interval=10s timeout=20s (dummy1-monitor-interval-10s)
 Resource: dummy2 (class=ocf provider=heartbeat type=Dummy)
  Meta Attrs: is-managed=false
              monitor interval=10s timeout=20s (dummy2-monitor-interval-10s)
