[Pulp-dev] Pulp 3 Default Ports

[Eric Helms]

I'm fine if someone wants to take up the effort to find and suggest two
ports that match all of those as the defaults. I've already opened a PR to
make port customization a reality. In most environments, these ports won't
see the light of day as they will be running services on localhost with a
webserver proxying to them. I was aiming for sane defaults, that users and
developers could easily rely on and expect across basic environments. And
allow customization in environments that need it.
