Brod producer connection terminates/fails without logging reason

[kjellwinblad]

How to reproduce:

Install docker and docker-compose

Do the following

git clone https://github.com/kjellwinblad/brod_gssapi.git
cd brod_gssapi
git checkout origin/kjell/example_not_working -b kjell/example_not_working
cd example
./up
docker-compose up brod_client

The last command runs brod_client/src/example.erl. It will fail when running the line brod:produce_sync_offset(client1, Topic, Partition, <<"FistKey">>, <<"FirstValue">>) which is ok since the Kafka server's advertised.listeners configuration is badly configured. However, we only get the error reason:

{reached_max_retries,no_leader_connection}

Expected Result

A logging message is produced every time the producer's connection fails with as much information as possible (the address and port it tries to connect to and if possible the reason for the failure etc). In the above example the log entry should contain the following info:

{error,{{sasl_auth_error,{sasl_fail,<<"SASL(-1): generic failure: GSSAPI Error: Unspecified GSS failure.  Minor code may provid"...>>}},
