wiki page for github pull requests

[chris snow <ch...@gmail.com>]

Hi Guys,

I think we need to add a new page to the WIKI for committers who want
to merge github pull requests into the apache git repository.

Where do you think the page should go?

Many thanks,

Chris

# These instructions assume that you have the apache git repo checked out

git checkout master
git remote add github https://github.com/apache/stratos.git
git fetch github # is this needed?
git fetch github pull/2/head:pr-2  # 2 is the PR number, pr-2 is a new
branch to create
git checkout pr-2

# push to apache git stratos repo master branch
git push origin pr-2:master

 # push to apache git stratos repo 4.0.0 branch
git push origin pr-2:4.0.0
