Add NodePorts filtering with development environment basis
This patch has not made "sslendpoints" fully compatible with
"check_for_nonssl_endpoints.sh" script yet. It sets up basic development

Tool output will be added to the README after reaching full
compatibility with previous (script) version.
Development environment brought by this patch is heavily based on:
