feat(local): Add mirror mode

[soar]

what

This PR adds support for cloning in the mirror mode (git clone --mirror)

The config will be slightly different. For bare repositories:

[core]
	bare = true
[remote "origin"]
	url = git@github.com:....git
	fetch = +refs/heads/*:refs/remotes/origin/*
[branch "master"]
	remote = origin
	merge = refs/heads/master

For mirror:

[core]
	bare = true
[remote "origin"]
	url = git@github.com:....git
	fetch = +refs/*:refs/*
	mirror = true

why

Mirror mode can be considered a better alternative for bare repositories to use as backups, as it is easier and more convenient

I like the idea but you only added mirror to git commands. Can you also add it to the go-git part in local.go?

@cooperspencer Isn't this what you are requesting?

Oh you are correct. Sorry, I overlooked that... I'll merge it.
