Enable GitHub discussions

[andygrove]

What is the problem the feature request solves?

During the public Comet meeting this morning we discussed enabling GitHub discussions as a place for people to ask questions and also potentially as a place to record notes from meetings.

We would be careful not to use discussions to make any decisions because discussions do not get sent to the mailing list (but all activity on issues and PRs do go to the mailing list, so this is where we make most decisions).

In order to enable the discussions feature, I will need to file an issue with ASF INFRA and will need to provide a link to a "consensus discussion thread". I will start a thread on the mailing list for this purpose.
