[iisue 80] - Add EAP 7 provisioning tooling

[fabiobrz]

Is your feature request related to a problem? Please describe.
Follows up on https://github.com/Intersmash/intersmash/pull/70 - in the context of using Intersmash with productized bits and deliverables, see #62

This is mainly needed to use Intersmash for testing the EAP 7 stream.

Describe the solution you'd like

• EAP 7 Image provisioner: Done, see [issue 80] - Adding the EAP 7.z (i.e. Jakarta EE 8 base WildFly) image provisioner #98
• EAP 7 Template based provisioner: Done, see [issue 80] - Adding EAP 7.z template provisioner #104
• EAP 7 s2i Build provisioner - Done, see [issue 80] - Add EAP 7 legacy s2i build provisioner #106

Describe alternatives you've considered
Rework internal tests that are currently using EAP image and template based provisioners in order to use different ones but that would require for more work and time.
