JAVA_OPTS doesn't work the way that the docs indicate

It took me a while to figure out why the above wasn't working. JAVA_OPTS is not understood by the JVM, but it is up to the application to read the env variable and do something with it.

What finally clued me in was using this very handy tool - https://github.com/ChristopherSchultz/ssltest

If I specified paths to the key stores using command line args, everything worked. But using JAVA_OPTS didn't. However, once I passed the -D arguments on the command line everything worked as expected. You can see the same thing here - https://github.com/lukebakken/rabbitmq-users-CzgiqOUso2k/blob/main/consumer/Dockerfile#L8

We could either make PerfTest read and parse the JAVA_OPTS env var if it's set, or I could amend the examples to show how to correctly use the -D JVM arguments.

Yes, there's something wrong there, JAVA_OPTS is an environment variable that Tomcat uses, I don't know why we ended up mentioning it here, maybe because the initial issue was related to the usage of PerfTest in a web container. I'll change the documentation.
