Support SASL/OAuthBearer Authentication

[oulydna]

Kafka supports SASL/OAuthBearer as an authentication method KIP-255.

We would really like to have this feature in this library to avoid a separate auth flow for Kafka from other pieces in our environment. So I am creating this issue to get the ball rolling (unless it's already being worked on or planned).

Do we have any plan or not for this?

@oulydna Hi there, for now I don't have any plans to work actively on adding it, but will happily review or assist if someone is willing to take a stab at it)

Thanks @tvoinarovskyi for confirming that. Having a PR coming your way.
