[JBTM-4011] Move vertx module to quickstarts

Manuel Finelli opened JBTM-4011 and commented

The Vert.x module in the Narayana codebase, which demonstrates the use of the STM implementation within a Vert.x 3 environment, would be more appropriately housed in the quickstart repository.

I will try to deprecate and remove the vertx module directly, and only if that is unfeasible I will consider moving it to the quickstart repository.
