Write a user supplied Profile to Git

[cre8minus1]

As an Arlon user with my own Profile (or Platform9 example) I would like to use Arlon to write the Profile directly to Git

So that i do not need to install and use seperate Git tools. Having this in the Arlonctl will help streamline my work processes.

for example: Arlon profile commit myFancyProfile -f http://github.com/pf9example/profiles/baseapps.yaml
