    Description

      When the Syndesis is running on OCP 4.5, it is not able to auto-discover a Kafka broker. When I want to create Kafka connection and I click on Kafka Broker URIs dropdown, i don't see any instance and in the syndesis-meta pod is following message:

      2020-08-19 12:02:41.913  WARN 1 --- [  XNIO-1 task-1] i.s.c.kafka.KafkaMetaDataRetrieval       : Couldn't auto discover any broker
      

      When I try this use case (from Steps to Reproduce) on OCP 4.4, everything works (The broker is discovered by Fuse Online).

      Reproducible on CRC as well.
      CRC 1.12.0 => OCP 4.4.8 (autodiscovery works)
      CRC 1.14.0 => OCP 4.5.4 (autodiscovery doesn't work)
