git improvements: testers wanted

The Systems team has been working on making clone/pull operations work better for people in different geographical regions:

https://wiki.linaro.org/Platform/Systems/GitHA

We currently have a DNS test alias named "git-geo.linaro.org" that should direct users to the server that will deliver the best connection. Before switching over the real "git.linaro.org" DNS entry, I was hoping to get some more people using this new system to verify its working correctly.

= How you can help

1) update "git.linaro.org" entries in your .git/config files to be "git-geo.linaro.org"

2) let me know how it goes for you
