[ADD] run-in command

[legalsylvain]

Hi all.

first, thanks for this great tool.

I propose an addition to git-aggregator lib: the command show-status.
Basically, gitaggregate will call git status -short for all the listed repositories and display result, if there are some local changes.

Call Sample:

gitaggregate show-status -c repos.yaml

Result Sample:

(INFO) [11:04:04] git_aggregator.repo  pos   Repo /opt/grap_dev/grap-odoo-env-8.0/src/pos: 3 changes found.
    R  pos_margin/__openerp__.py -> pos_margin/__manifest__.py
    R  pos_order_load/__openerp__.py -> pos_order_load/__manifest__.py
    ?? test/

Hi @legalsylvain thanks for the contrib.

The function could be useful but sounds quite specific. If we add this, I'd fear it would open the door to an infinite stream of requests for new git commands.

Why not a run-in command or something similar that would run an arbitrary shell command in each repo?

Like git-aggregate -c repos.yml run-in -- git show-status --short ?

I @sbidoul, thanks for your review. your suggestion seems valid. I don't know exactly how to implement the --, but I developped something similar.

Sample :

gitaggregate run-in --run-in-command 'git status --short'

result :

(INFO) [11:04:04] git_aggregator.repo  pos   Repo /opt/grap_dev/grap-odoo-env-8.0/src/pos :
    R  pos_margin/__openerp__.py -> pos_margin/__manifest__.py
    R  pos_order_load/__openerp__.py -> pos_order_load/__manifest__.py
    ?? test/

@legalsylvain based on #38, you can do this:

    run_in_parser = sub_parsers.add_parser(
        'run-in',
        help="..."
    )
    run_in_parser.add_argument(
        'run_in_command',
        nargs='+',
    )

And then subprocess.call(args.run_in_command)
