Check/get ingress port on add-on load

[agners]

Proposed change

Instead of setting the ingress port on install, make sure to set the port when the add-on gets loaded (on Supervisor startup and before installation). This is necessary since a dynamic ingress port is not stored as part of the add-on data storage themself but in the ingress data store. So on every Supervisor start the port needs to be transferred to the add-on model.

Note that we still need to check the port on add-on update since the add-on potentially added (dynamic) ingress on update. Same applies to add-on restore (the restored version might use a dynamic ingress port).

This addresses the following issue seen on the dev channel:
