Add support for git clone transport protocol

This release adds support for detecting the protocol from the githooks.json file. Previously it was assuming all connections are going over https. Now they can go over ssh as well.
Example structure:

{
    "pre-commit": {
        "ssh://git@my.git.repo:org/repo": [
            "script1"
        ],
        "https://my.git.repo/org/repo": [
            "script1"
        ],
        "my.git.repo/org/repo": [
            "script1"
        ]
    }
}
