Add test environment for activemq

[mgarabed]

What does this PR do?

In preparation for creating a native dashboard for ActiveMQ, this PR provides a basic E2E environment where JMX metrics can be extracted.

Additional Notes

Once the env has been started via ddev env start activemq py37, you can access the admin interface at the following url: http://localhost:8161/admin/

From there, you can add new queues or topics, then run ddev env check activemq py37 and see updated metrics in the output.
