Description of problem:

must-gather from local-storage-operator contains only the local-storage namespace. This does not allow us to debug why a perfectly looking DaemonSet does not start any Pods, because we don't have Nodes, with their taints and labels. In addition, listing LocalVolume PVs might be useful too.

Version-Release number of selected component (if applicable): any

How reproducible: always

Steps to Reproduce:

1. Install LSO, create LocalDisk
2. Grab LSO must-gather, oc adm must-gather --image=registry.redhat.io/openshift4/ose-local-storage-mustgather-rhel8:v<installed_version_LSO>

Actual results: No nodes.yaml, no pvs.yaml

Expected results: nodes.yaml with all their taints, labels and statuses and pvs.yaml with all volumes provisioned by LSO, if there is a label that could be used to select them (all PVs otherwise).
