This implements remote port detection for services running in uncloud, when you proxy to them you only need to give the service name and proxy will figure it out.

This does not cross reference with x-ports, nor does check the expose syntax (for the love of it, I couldn't find where to add that). This also means adding/remove expose ports isn't detected as a service change.

Having said that, it works beautifully:

% ./uc proxy debug
http://127.0.0.1:44345 → 10.210.0.19:80 (debug/f33620ea40f3)

% ./uc proxy debug 12334:
http://127.0.0.1:12334 → 10.210.0.19:80 (debug/f33620ea40f3)

% ./uc proxy debug 80
http://127.0.0.1:39815 → 10.210.0.19:80 (debug/f33620ea40f3)

% ./uc proxy perses
http://127.0.0.1:42617 → 10.210.0.9:8080 (perses/6e51faac2888)

% ./uc proxy prometheus
http://127.0.0.1:44803 → 10.210.0.8:9090 (prometheus/709cf40d7305)

% ./uc proxy uniprune

I tend to get lost in the service vs servce container stuff - adding it in the place I though it would do something didn't matter; maybe you can easily fix that though
