Disable TLS usage (aka do not use /etc/apacheds/apacheds.jks)

[johanneskastl]

As stated in the other issue #9, I got the container image running in my Kubernetes cluster. But only by using a fake keystore file.

Would it be possible to change the run_apacheds.sh script to only configure TLS, if the file is present?

Sure, TLS should be a must, but depending on the use case (and testing seems to be the main use case) the user should decide if she wants to enable TLS or not.

If you are fine with the idea, I would prepare a PR to modify the script.

If you're open to writing a PR, sure.
