must-gather improvements

1. from https://issues.redhat.com/browse/RFE-1576 add output compression
2. from earlier discussion about escalation add --since to limit the size of data (https://issues.redhat.com/browse/RFE-309)
3. from workloads architecture must-gather fallback to oc adm inspect clusteroperators when it can't run a pod (https://github.com/openshift/oc/pull/749)
4. ability to get kubelet logs, refer to https://bugzilla.redhat.com/show_bug.cgi?id=1925328 (no longer relevant, feel free to reopen/re-report if needed)
5. fix error output from sync, see https://bugzilla.redhat.com/show_bug.cgi?id=1917850
6. Create link between nodes and pods from their respective nodes, so it's easier to navigate. (no longer applies)
7. Gather limited (x past hours/days) of logs see https://bugzilla.redhat.com/show_bug.cgi?id=1928468.
8. Use rsync for copying data off of pod see https://github.com/openshift/must-gather/pull/263#issuecomment-967024141 (moved under https://issues.redhat.com/browse/WRKLDS-1191)

[bug] Must-gather logs (not longed into the archive) - this also applies to inspect
[bug] timeouts don’t seem to happen at 10 min
[RFE] logging the collection of inspect in the timestamp file - the timestamp file should have more detailed information, probably similar to the first bug above (moved to https://issues.redhat.com/browse/WRKLDS-1190)
