Release/flocker 0.3.0dev1

Fixes #879 
Ah yes, you're right.

"Merge the release branch. Merge release branch and close the release pull request." is at the end of the "Release" section which is blocked by accepting this PR. So this PR should have that as a note on it, something like "Accept but do not merge until the 'Release' process has been finished". If that sounds right please also add it to the release docs in the improvement branch.
