Add OtherResources table to the operator view

[andresmgot]

Description of the change

Add the Other Resources table to the Operator view to complete the view:

Note that even though we are just interested on knowing the name of the resources, we need to request the list of resources (in a namespace) and filter out.

There are a few tricky things in this PR:

1. Some resources listed are not shown later. For example, an Operator may define Pods as one of the resource it creates but since those pods are not directly linked to the Operator CRD (the Deployment is instead), these resources are not shown in the table.
2. Apart from the current workaround of guessing the apiVersion/plural, I needed to differentiate between namespaced and non-namespaced resources. This is becoming too hacky... but would work now for the alpha release.

To avoid any issues with the current approach for charts, we are maintaining the old behavior for helm releases (not requesting nor watching "other resources").
