Package suggested git script with Python package

[joao-p-marques]

As suggested in acsone/git-aggregator#55

@sbidoul @yajo this solves the problem by using a pure Bash script. However, I still haven't found a way of making it optional on install... Any ideas?

Some notes on what was already explored:

1. A Python script to replace the git command is not viable due to Python load times.
2. setuptools allows you to define optional commands to be insatalled, but AFAIK only through entry_points, which is only meant for Python modules.
3. I tried packaging a Python script that would only override git clone (git-clone) as that would not introduce more delays that autoshare itself and it would only affect the clone operation. However, even when I have git-clone in the path, git clone still redirects to the normal command. I guess it is one of those subcommands that can't be replaced...

The only idea I might have is to create a separate package with only the bash script and depend on it in an extra. But... meh.
Also I'm not sure of the status of setuptools scripts. I'd need to check.

@sbidoul Maybe not the most elegant solution, but I just added the option to explicitly opt-in to the script replacement through a shell variable...

We don't want to affect people with git in other paths.

Suggested change

	/usr/bin/git autoshare-clone "$@"
	"$0" autoshare-clone "$@"

[yajo]

Suggested change

	/usr/bin/git "$@"
	"$0" "$@"

[joao-p-marques]

This won't work I am afraid, as $0 (git) will resolve to the current script and cause a loop...

Maybe shomething like

Suggested change

	/usr/bin/git "$@"
	${GIT_BIN:-/usr/bin/git} "$@"
