UI representation for `Roles`

[KaradzaJuraj]

Some K8s components are supported to have a custom UI component, and those can be found here. The scope of this issue is to support Roles. The new Roles component should be similar to other components we already have, so feel free to check the existing ones out.

The visual representation should look something like this:

You can fetch the data about a role by calling the backend on

/api/resources?group=rbac.authorization.k8s.io&version=v1&kind=Role&name=<name>&namespace=<namespace>

You can test this using the rabbitmq default template, for example (the above image was created using this template!).
