story #7514 - have grokmirror hook activated

For selected repositories, it will trigger execution of grokmirror-manifest.

The resulting manifest file will be then published in /var/lib/tuleap/gitolite/grokmirror

You will also need to deploy plugins/git/etc/httpd/grokmirror.conf in
/etc/httpd/conf.d/tuleap-plugins and restart apache so your mirror can fetch
the manifest file

For dev, you need to redeploy your git-post-receive.pl:
install -m 06755 -o codendiadm -g codendiadm /usr/share/tuleap/plugins/git/bin/git-post-receive.pl /usr/lib/codendi/bin/git-post-receive.pl

You will also need to install python-grokmirror package from EPEL (centos 6)
