Improve variables support
What does this MR do?
These are random changes extracted from other code that I work on now: https://dev.gitlab.org/gitlab/gitlabhq/merge_requests/2563.
This slightly improves variable support, ensuring, that we always pass strings.
This also slightly improves KubernetesNamespace ensuring that namespace
and service-account-token
are always set.
