Passwords and certs must be randomly generated

[dlohin]

All default passwords must be randomly created and use secrets, particularly for internal services for all inter-pod communication.

Passwords will be generated by the Helm charts and then stored as secrets that can then be "shared" between the tools. For example, Logstash to Elasticsearch has a password. The process should be generate password with the Elasticsearch tool and then Logstash can reference and consume this secret.
