Tin Lam 628fd3007d RBAC: Consolidate serviceaccounts and restrict rbac
Currently, services have two serviceaccounts: one specified in the
chart that cannot read anything, and one injected via helm-toolkit
that can read everything. This patch set refactors the logic to:

- cleanup the roles and their binding automatically when the helm
  chart is deleted;
- remove the need to separately mount a serviceaccount  with secret;
- better handling of namespaces resource restriction.
