Owner API port should be configurable

[alesito85]

Currently it only listens on 13420 without the possibility to change unless one changes source and compiles.

[quentinlesceller]

You mean you'd like to be able to change the owner api from local 13420 to local another port?

[yeastplume]

This is intentional, see #1867

[quentinlesceller]

@yeastplume It seems like @alesito85 wanted to change only the API port and not the address? Which should be fine?

[yeastplume]

Yes, sorry, I read too hastily.

[alesito85]

As @quentinlesceller said, I'd like to configure just the port.
