Enable Discussion Forum.

Hello,

It would be great to have a discussion option in Github as some of my questions are not bug report rather clarifications or just asking another member for their input.

Can we please enable discussion forum in this GitHub repo.

Thanks.

This issue is for a: (mark with an x)

- [ ] bug report -> please search issues before submitting
- [X] feature request
- [ ] documentation issue or request
- [ ] regression (a behavior that used to work and stopped in a new release)
