Thanks Jeremy and Hervé!

@Jeremy, @Hervé: I've checked and found two open patches, out of which I 
was able to abandon one, and asked the owner on the other patch to 
abandon it. So the listed branches can be deleted *except* one: 
openstack/os-collect-config

So in my opinion there's no need for further coordination with the 
teams, as these branches are tagged ocata-eol already.

And thanks Hervé for the script, it helped a lot so far, already :) + 
thanks Jeremy for the pointers!
