The current `oc adm inspect --all-namespaces` command line results in something like this:

oc adm inspect --dest-dir must-gather --rotated-pod-logs csistoragecapacities ns/assisted-installer leases --all-namespaces

Which is wrong because of 2 reasons:
- The `ns/assisted-installer` is there although a namespace is not namespaced, so it should go to the `named_resources` variable (this happens only in 4.16+)
- The rest of the items on `all_ns_resources` variable are group resources, but they are not separated by `,` like we do with `group_resources` (this happens on 4.14+)

As a result, we never collect what is intended with this command.

Any 4.14+ version

Always

    1. Get a must-gather
    2.
    3.
