LGTM. As I already reviewed this in https://github.com/datacenter/aci-ansible

The integration tests require ACI infrastructure, but we are going to add them as soon as possible in a form acceptable to this project. Working on it.

@privateip @devarshishah3 @jedelman8 @calfonso Your feedback is appreciated.

As this module is the first module in a larger set, so any feedback we can take into account for the other modules.
