[ClusterLabs] A note for digimer re: qdevice documentation

[Steven Levine]

I'm having some trouble re-registering for the Clusterlabs IRC channel 
but this might get to you.

Red Hat's overview documentation of qdevice (quorum device when spelled 
out in the doc) is here:

https://access.redhat.com/documentation/en-us/red_hat_enterprise_linux/8/html-single/configuring_and_managing_high_availability_clusters/index#assembly_configuring-quorum-devices-configuring-cluster-quorum
