Remove flavor section as it's confusing for users and not actually accurate

[jbonofre]

We have two subprojects on the ActiveMQ TLP, each with release cycle, roadmap, ...

Users are confused with this statement. I propose to remove it. Users can evaluate themselves and decide to use one or another as both are still maintained.

@jbertram @cshannon @mattrpav wdyt ?

It seems like we should probably remove the statement as it is no longer accurate since both brokers are maintained as you said independently and probably will be for the forseeable future

I think we should probably have a larger discussion on the dev list before making this change. For what it's worth, I haven't seen any confusion about this on the mailing lists, Slack, or Stack Overflow so it would be worth discussing exactly who is confused by this and why. As I understand it, the community goal since the acceptance of the Artemis donation was to take the best of both code-bases and consolidate development in order to build the best open-source message broker in the industry.

Regardless, nothing is stopping users from evaluating and making a decision about which broker to use. I do think it would be helpful to users to provide some kind of explicit guidance for which broker to use and why and to provide a vision for future development. I hope a discussion on the mailing list might provide some clarity here.
