Make Kafka URL an environment variable
We have created a separate Kafka instance for production deployment to avoid mixing dev and prod notifications. Please make a Kafka URL an environment variable (currently it's hardcoded as https://test.ncbi.nlm.nih.gov/books/kafka/), so we could specify a different URL for dev and prod in NCBI GitLab CI/CD settings.
QA Steps
Mostly consists of testing that the changes haven't affected component status updates.
