I'm not able to connect to Kafka server when the BOOTSTRAP_BROKER is a FQDN with a dot at the end.
Different Kafka implementation provide endpoints with a dot at the end so you can use a BOOTSTRAP_BROKER without dot at the end but you ad not able to connect to the topic anyway.

Hi team based on the discussion in openssl/openssl#11560 (comment) would it be reasonable to accept the change in behavior for ignoring the trailing . in the FQDN? Also see this here: #4348. Although folks have worked around this already it does seem like the proper behavior to follow.

@emasab Any chance we could get your take on this PR? This seems like valid behavior to have and check for in the client and doesn't sound like would break existing behavior.
