When we modify env_config, that is on the global Rails.application, and
we need to stub it and allow it to be modified in-place, without
polluting later tests.

When we modify env, then the context is a request, or something else
that only lives for a single spec.

The disabling of Gitaly was basically stubbing `Feature.enabled?` call,
which was never triggered.

This ensures that variables accept only string,
alongside also improves kubernetes_namespace,
improving validation and default value being set.

Private commit emails were introduced in !22560, but some parts of
GitLab were not updated to take account of them. This commit adds
support in places that were missed.
