Support git as a source of mock templates

Prerequisites

• I have written a descriptive issue title
• I have searched existing issues to ensure a similar issue has not already been created

Description

Currently, Mockaco supports only a file based source of mock templates. It would be nice to have a way to version mock templates in a centralized repository.

Proposed solution

Integrate with git and support a source path like git://xxxxx.git.com/my-mocks.git

Alternatives

• http url could also be a source of mocks (how to list files?)
• database?
