Remove address scopes from supported extensions

Remove address scopes from supported extensions

This feature is not ready for prime time, but the cli code is
already landed and shipped.

In order to prevent users from getting mad about an uncooked feature,
let's disable it until it becomes more robust.

Tests must be disabled unconditionally because our CI API test framework
execute tests for 'all' extensions available.
