Create a playground environment in a Github action

[achille-roussel]

We often receive incomplete bug reports, a lot of back and forth is needed just to get to being able to reproduce the issues, and often times the problems come from local configuration that we don't have access to.

Having a shared testing environment that both users and maintainers have access to would be extremely useful, and would allow us to define a workflow where bug reports must be supported by a reproduction in CI that all parties can access, including:

• zookeeper/kafka stack started automatically
• matrix of kafka versions
• logs published as artifacts of the CI run

Something to explore is whether users can leverage this mechanism in their own Github account via a fork of the kafka-go repository.
