Offer distinct Ansible versions

[fiunchinho]

This is a nice repository, but I miss the ability to choose between different Ansible versions, so test playbooks against different Ansible versions would be really easy.
I'd keep at least a different image for every minor version, like 1.9, 2.0, 2.1, and so on.

@fiunchinho I've added 2.2 version #26

Nice! Any chance to add other versions like 2.0 or 2.1?

@fiunchinho waiting for maintainers response, if he does not mind, I'll add other minor versions
