Move to Circle CI; Add integration tests against test dev jira project; release docker images

AC:

• Use this to create dev JIRA project https://developer.atlassian.com/blog/2016/04/cloud-ecosystem-dev-env/
• Implement integration tests against that
• Move to CircleCI (@free well, mostly because from my expierience it works bit better than Travis, plus Travis has some issues now)
• Add docker image release process on every master commit
