add agilezen.com service (BB-3490)

Hello,

I work for rally software, owner of agilezen.com and I am working on an integration for adding commit info to our users' projects when they make a commit to bitbucket. I would like to get the integration added to your services dropdown if at all possible.
In order for that to work, we would need two fields, one for "project id" and one for "api key". I have written a broker (which is based on the POST broker in your docs) which assumes that these two values come in as payload'service''projectId' and payload'service''apikey', which is attached.
Would you mind working with me to test and add this to your services list?

Thank you,
Ryan Curtis
