Can you also add explicitly subscribing to wildcard in this test?

I removed this test because it's already covered by the logic of the multiple types test. I added explict wildcard test to all of them, and added delta versions of the test.

I don't think passing Opts here is needed. Directly passing if legacy is deactivated is sufficient

I would remove those two methods and replace them with IsLegacyWildcardActive(typeURL)
This would allow extending/evolving the option interface without impacting code in the rest of the modules

Comment to rewrite. The sentence is inconsistent

Why is this passed in this interface? This is still leaking parameters here that have no value on the subscription

This PR add two new public facing xds options
DeactivateLegacyWildcardandDeactivateLegacyWildcardForTypes.This will allow users to disable legacy wildcard mode. This allows us to avoid returning all resources when envoy makes a VHDS request with an empty subscription list. It'll also allows us to ensure that we never return all resources to grpc-xds clients.
