Remove gerrit_set_agreements

The script was here for transition purposes, which are long-since
past. However, puppet runs it on every run. It's not hurting anything,
except for bunny rabbits.

-# The point of this script is to update the list of contributor license
-# agreements Gerrit knows about. More specifically, in its current form,
-# it's being used by Puppet to perform database-specific parts of a
-# migration for OpenStack's development and production Gerrit servers
-# from Echosign to a Gerrit-managed CLA. As such, a lot of this code can
-# be ripped out once that migration is complete (though it doesn't
-# necessarily need to be, and can be left in place more or less
-# indefinitely without impact).
-
-# This function takes a contributor agreement ID and returns 0 if Y
-# (active), 1 if N (inactive) or anything else (including if the CLA
-# does not exist). It would be nice to implement this by short name
-# instead, but Gerrit does not create the id column with auto_increment
-# so we have to know what ID integers we want when creating anyway.
