Configure performance monitoring in federated mode if > 1 node in the cluster

[mrolyat]

Need to configure performance monitoring to best practice and in redundant federated mode with multiple collector nodes.

4 node cluster 1 node marked as MGMT GUI (which flags as pmcollector)

# hosts:
[cluster01]
node-vm1 scale_cluster_quorum=true   scale_cluster_manager=true scale_cluster_gui=true
node-vm3 scale_cluster_quorum=true   scale_cluster_manager=true scale_cluster_gui=false
node-vm2 scale_cluster_quorum=true   scale_cluster_manager=true scale_cluster_gui=false
node-vm4 scale_cluster_quorum=false   scale_cluster_manager=false scale_cluster_gui=false

[root@node-vm1 ibm-spectrum-scale-install-infra]# mmdsh -f1 -N all rpm -qa | grep pmcollector
node-vm1.tuc.stglabs.ibm.com:  gpfs.gss.pmcollector-5.0.5-0.el8.x86_64
[root@node-vm1 ibm-spectrum-scale-install-infra]# mmdsh -f1 -N all rpm -qa | grep pmsensors
node-vm1.tuc.stglabs.ibm.com:  gpfs.gss.pmsensors-5.0.5-0.el8.x86_64
node-vm2.tuc.stglabs.ibm.com:  gpfs.gss.pmsensors-5.0.5-0.el8.x86_64
node-vm3.tuc.stglabs.ibm.com:  gpfs.gss.pmsensors-5.0.5-0.el8.x86_64
node-vm4.tuc.stglabs.ibm.com:  gpfs.gss.pmsensors-5.0.5-0.el8.x86_64

**Only one node is setup as a collector when there should be 2 nodes for redundancy:**
'''[root@node-vm1 ibm-spectrum-scale-install-infra]# /usr/lpp/mmfs/bin/mmperfmon config show | grep -i col
colCandidates = "node-vm1.tuc.stglabs.ibm.com"
colRedundancy = 1
collectors = {
