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.
