Improve genesis built system

[bugzmanov]

This is an epic related to proper artifact management in genesis.

Details to be provided.

The main idea: genesis is required to have notion of "application manifest" that should be stored with sources of application being deployed via genesis. The manifest should describe how to application should be build and what artifacts should be considered as result of the build (to be processed after deployment)

Good understanding why is this needed can be obtained from here:

As a start, I would suggest to support maven. But the system should be designed to scale to support any kind of building configuration: sbt, gradle, etc..
