        'helidon-webserver' has some optional dependencies that we don't need.

        Unfortunately, only some are listed as optional dependencies in the POM. But I'm curious, do I really need any
        of the following modules to run a hello world-style Helidon web server program?
          * 'helidon-common-configurable'
          * 'helidon-common-security'
          * 'helidon-common-tls

        The big thing we don't want is "helidon-config" because it's large (300K+) but the TLS module depends on it which
        I think is an oversight. I get this error when I ignore "helidon-config".
