Make Java Client Authentication Asynchronous

[michaeljmarshall]

Search before asking

• I searched in the issues and found nothing similar.

Motivation

The OAuth2 client's authenticate call is blocking, which is not great for the client, and is bad for the proxy because the proxy authenticates from a netty event loop.

Solution

In the same way that PIP 97 #12105 make the AuthenticationProvider async, we should update the Authentication interface.

Alternatives

No response

Anything else?

This change will likely require a PIP. I am unable to write such a PIP at this time, so I am creating this issue to keep track of this missing feature.

We could make a PIP, though I don't have time to work on it right now.

Hey @tisonkun Thank you for assigning.
I think this will be achieved using Java Completetable future.
we have to update the interfaces such as AuthenticationProvider, AuthenticationState, and AuthenticationDataSource.
I am not sure about the module. I need little clarification to get started asap.
