pubsub: add Subscription.PushConfig.AuthenticationMethod

Adds Subscription.PushConfig.AuthenticationMethod which is
a one-of field hence the use of an interface
`AuthenticationMethod`. This field is optional
and only part of a closed alpha.
The only currently supported AuthenticationMethod is
"OIDCToken" (OpenID Connect Token), which has been added.

This change adds an example too as well roundtrip tests.

Updates #1361
