This PR includes a new Role resource version that is compatible with V5 spec.
The new resource introduces the `kubernetes_resources` definition that allows operators to limit the Kubernetes resources that each member can access. The `kubernetes_resources` entries must follow the following format: `{"kind":"<kind>", "namespace":"<namespace>","name":"<pod>"}`. Currently, it only supports objects of `kind` `pod`. Valid examples `<namespace>/<name>:
- `*/*`: matches all pods in all namespaces.
- `default/*`: matches all pods in the `default` namespace.
- `*/nginx-*`: matches every pod prefixed with `nginx-` in every namespace.
For older resource versions - V5, V4, V3 - `kubernetes_resources` is automatically populated with `{"kind":"pod","namespace":"*","name":"*"}` to keep compatibility. For the newest version, it's mandatory to define its value otherwise access to pods will be denied.
Part of #18434
Update metalinter, fix a few lint warnings and replace deprecated linters.
`deadcode`, `structcheck` and `varcheck` are abandoned and now replaced by [`unused`][1].
Since 1.19, `go fmt` reformats godocs according to https://go.dev/doc/comment. I've done a bulk-reformatting of the codebase to keep the linter happy. Backporting is mostly harmless (the exception being `lib/services/role_test.go`, that for some reason breaks the _old_ linter using the new format).

Introduce new make targets to check and add license headers to files
("make lint-license" and "make fix-license"). License checking is now a part of
"make lint" as well.
Initial attempts used goheader, but it caused "make lint-go" to become about 9x
slower (if not more), plus it only targets go files. Google's addlicense is fast
enough and targets however many file types we want.
Existing files that were missing licenses got the header added, using the
current year as the license date.
* Introduce lint-license and fix-license make targets
* Ignore generated files
* Add license to go files
* Replace irregular licenses with standard copyright/license
* Add license to proto files
