Describe the problem you'd like to have solved

Currently some OkHttp deps of third party libs in my project are upgraded to 5.x (5.0.0.Alpha14), which will break the APIs in the auth0-java which used an old Okhttp.

Describe the ideal solution

I would like there is a new branch for the future development, and also upgrade the code style and code base to modern java that align with the popular frameworks.

Upgrade codes to Java 17.
Upgrade OkHttp to 5.x
Add ReactiveStreams/Java 9 Flow.Publisher and Kotlin Coroutines support.
