Make git repository setup optional

[martinratinaud]

As use can choose mongo OR git as a database system, there may be no need to create nor define repositories url.

Let's make it optional

Tested on vagrant

• add ota_branch: conditional_git_repo_ops_test in dev.yml
• commented snapshots_repository in dev.yml
• replace "type": "git", by "type": "mongo" in default.yml
• deployed with ansible-playbook -i ops/inventories/dev.yml ops/site.yml
• SSH to machine vagrant ssh
• snapshots folder is not present

Tested locally. It works.
We just got this error:

Either specify the URL from the command-line or configure a remote repository using

    git remote add <name> <url>

and then push using the remote name

    git push <name>

It's due to the fact that the engine try to push on a non existent remote. I will open an issue for this.
