feat(argo-cd): adds toggle for helm-working-dir (#2249)

- Adds a toggle to be able to turn off the helm-working-dir for the
  repo server deployment. Using a shared helm repo storage directory can
  cause issues when multiple helm commands are being run in parallel.
  The repo server also has the ability to rebuild the repos and do
  updates in the normal flow for checking the status of an application
  so it won't cause issues if it's disabled.
