uralkal: deliver kafka creds for issues, flows and pm from kafka-topics

Step 2 of 2 - push only after the pipeline for the previous commit has
applied. secrets[] writes kafka/apps/issues and kafka/apps/flows (user proc)
and kafka/apps/pm (user pm) from the kafka-topics outputs, so the password
in Vault is the one actually set in the broker. Fields are flat
(username, password, sasl_mechanism, ...), there is no nested auth map.
