1. Adding missing handler getToken in case of no-orch
2. In case of multi_tenancy is disabled, if we get authentication error from API
Server, then do not redirect to logout, in stead pass the error object to
handler, redirect to logout only if multi_tenancy is enabled and we get
authentication error.
