If the service fails mid-point, then we should be able to re-run this
service. So, detect presence of any previously created Kubernetes
resource and update or create accordingly.
Fix specs accordingly. In the case of finalize_creation_service_spec.rb,
I decided to stub out the async worker rather than maintaining
individual stubs for various kubeclient calls for that worker.
Also add test cases for group clusters
This removes the ability to pass in a different version. We can instead
create a new entry in the SUPPORTED_API_GROUPS hash for a different
version if need be.
We should have access to #core_client, #rbac_client,
and #extensions_client without having to pass in an awkward array.
Also change api_version to default_api_version, which allows us to use a
different version for an individual client. Special case for
apis/extensions which only go up to v1beta1
Makes #hashed_client private
Removes the #clients and #discover! methods which are un-used
This also solves the async nature of the automatic creation of default
service tokens for service accounts. It also makes explicit which
service account token we always use.
create cluster role binding only if the provider has legacy_abac
disabled.
