[common] Gluetun web api

[emanuellopes]

Is your feature request related to a problem?

There is a way to allow define a custom port to access to gluetun http Portal.
This will allow to add the gluetun rest api in uptime kuma and monitorize if vpn is down or up.

Describe the solution you'd like

Allow define a custom port when we add the gluetun vpn in our container.

this can be manually done on your end by adding the variables if needed to gluetun and just add a custom port to the services section of your helm chart/helm-release file if using fluxcd.

there are various ways to achieve this on your own....and if youre referring to scale specifically that is deprecated sadly but you can still add the options to it.

what platform are you on, as i can only assume this was done in april...that you were/are on scale?
