[Gluster-infra] Standalone git-daemon setup for the Gerrit repositories on r.g.o

[Kaushal M]

Hi all,

I've setup a standalone git-daemon sever to serve the Gerrit git
repositories on review.gluster.org over the anonymous git:// protocol.
The GlusterFS repository can now be accessed using
git://review.gluster.org/glusterfs.git as the remote.

I've changed the Jenkins job configurations for linux regression,
netbsd regression and all the smoke jobs, to use this address instead
of the ssh:// or http:// . This reduces load on Gerrit, as the http
and ssh git access is served by the gerrit daemon itself.

Though an anonymous git export was available earlier, it didn't point
to the Gerrit repositories, but instead pointed to a mirror on the
same system, which contained just the release branches. Because of
this the jenkins jobs couldn't download the changes under review to
run tests on.

This should improve some of the Gerrit issues being observed, mainly
the 'server unavailable' errors.

Cheers,
Kaushal
