Add ExtraAudience option to RoundTripper to allow operators to include
additional audiences (e.g., provisioning group) when connecting to the
multitenant aggregator. This ensures tokens include both the target API
server's audience and the provisioning group audience, which is required
to pass the enforceManagerProperties check.
- Add ExtraAudience RoundTripperOption
