oc like tool that works with must-gather rather than OpenShift API
Simply run:
$ pip3 install o-must-gather --user
Point it to an extracted must-gather:
$ omg use </path/to/must-gather/>
Use it like oc:
# omg get clusterVersion
# omg get clusterOperators
# omg project openshift-ingress
# omg get pods -o wide
