Set up two-stage CD pipeline in IBM Cloud

[nicksome168]

As a developer I need my application to test and deploy continuously automatically So that I don't have to run nosetests separately and re-deploy each time

Details and Assumptions

• Connect DevOps pipeline to github repo (done by owner of repo)
• Add 2 stages: build (incl. test), deploy
• Add build stage to checkout code from github, run unit tests with green
• Add build stage job to build docker image and push it to IBM Cloud container registry
• Add Dev Deploy stage to deploy microservice to dev namespace in kubernetes cluster

Acceptance Criteria

Given  that CI/CD has been implemented properly
When the master branch changes
Then nosetests is run, docker image is built and pushed to cloud container registry, microservice is deployed to dev namespace, integration test is run with behave, prod namespace is deployed if all tests pass
