Revert !949

Based on conversation on #457 (closed), revert !949 (merged). High level summary, !949 (merged) assumed the problem described in #457 (closed) was coming from the kafka producers set up in the kafka bootstep, but we found later it was coming from the IGWN-Alert client. This problem was then dealt with in !958 (merged) / !960 (merged).
