Vapor API Scaffold (#2)

* Updated README

* Start of Vapor Netbox Module

* Add api/vapor route

* Ignore virtualenv

* Query devices assigned to users

* Add vapor/interfaces route

* adds docker-compose file to manage postgres/redis

- Initial test suite for the vapor api module. (Django tests are kind of
  hard and slow)

* Init pipeline

 - Adds a tox harness to run the test suite
 - Test running in tox
 - Clone example config to config.py
 - Add the kubernetes agent + dependent services to complete tests in
   the podspec
 - some really hacky sed configuration on the fly

* Init Docker build

- Adds the dockerfile assets from vapor-ware/netbox-docker
- Slight changes to keep the root directory clean (nesting dirs in
  docker path)
- Adds a rudimentary job label to build on micro-k8s builder
- adds docker build/publish stages to the pipeline for branch builds.
- dockerignore the project dir as its fetching packages from GHAPI

* Cleanups

* More unittests
