Storlets/Release Branch Creation

This is a temporary procedure till we are "Big Teneted"

1. Create a patch that pins the dependencies (updating CHANGELOG while at it)
2. create the tag for the branch (Make sure your .gitconfig is up-to-date with e.g. the gpg signingkey entry):

git tag -m "stable/newton tag" -s 0.3.0

1. Push the tag: git push gerrit 0.3.0
2. Create the branch

git branch -b stable/newton git push gerrit stable/newton
