Created branch v0.2.0 for release close down

[Kevin Minder]

Hi Everyone,
I created a branch (v0.2.0) for release close down.
To clone the branch into a new repo <directory> use this command.

git clone --branch v0.2.0 
https://git-wip-us.apache.org/repos/asf/incubator-knox.git <directory>

To switch to the branch in an existing repo use these commands.

git fetch
git checkout --track --branch v0.2.0 origin/v0.2.0

Kevin.
