Support storing sensitive notification settings securely/encrypted.
Move slack notifier url and api token to secure settings.
Migrating slack notifier to store token and url encrypted is currently 
a manual process by saving an existing slack alert notification channel.
saving an existing slack alert notification channel will reset the stored 
non-secure url and token.

Imagestore: Fallback to application default credentials when no key file is specified for GCS (#25948)

The external image storage for GCS creates the JWT Token from a credentials file, 
but if your Grafana server runs under a GCE instance with a service account on it, 
you can use that instead (you don't have to manage/secure the credentials file).
