This patch introduces "/repository:size" quota group that gets examined
when commits get pushed to the repository. It moves the responsibility of
quota check to Gerrit core so that implementation details don't have to
be exploited by quota plugin.
Pros:
* simplified implementation of quota plugin (only QuotaEnforcer needs
to be implemented)
* better compatibility in long term (quota plugin doesn't have to
recognise all the places when it is necessary to hook into in order
to deliver repository size quota functionality)
