Add support for Openwhisk

[lordofthejars]

Issue Overview

Add support for Openwhisk so you can install a function/s, run the tests and delete the function/s.

Two modes should be supported by the assistant one (programmatic) and use @Deployment (declarative).

It should be work not just with java/jar files but also python or javascript.

In the future, we could also provide support for creating a temporal namespace, install openwhisk, install function/s, run tests, delete temporal namespace.
