This is a followup of WFLY-15283 and makes sense only in case that relevant PR https://github.com/wildfly/wildfly/pull/14665 is merged as is now - with key/trust stores pre-generated and hardcoded in the git.

It would be nice to generate these files dynamically for the test so they are not part of the repository, is it easier to update them when changing some tests attributes, they don't expire, etc.

I believe this is the preferable option now. Please, let me know if that is not true.
