In the Google Cloud Storage backend, support specifying access tokens directly, as an alternative to a credentials file. This is useful when restic is used non-interactively by some other program that is already authenticated and eliminates the need to store long lived credentials. The access token is specified in the GOOGLE_ACCESS_TOKEN environment variable and takes precedence over GOOGLE_APPLICATION_CREDENTIALS.
