Remove allocation of multiple HTTP ports at startup

Proposal

When installing Maesh, the number of HTTP ports that should be allocated for mapping must be defined at startup. As we are using the router rule Host in Traefik to multiplex the allocated ports, there is no special reason to allocate a bunch of ports at startup. We have to be careful because this change might be breaking.

Btw, the current algorithm we use will multiplex the first allocated port in most cases.

If a service exposes 2 ports we still need to distinguish svc.ns.maesh:8080 and svc.ns.maesh:8081. We have to keep it as it is.
