Improve Makefile in all repos

[dpanayotov]

Makefile can be improved in all repositories:

1. Build docker images.
2. Add version flag from commit
3. gofmt
4. push to k8s & cf / run locally
5. flags to go test
6. make release that increases the version in all necessary files, creates a tag and pushes to github
