Add Web-UI Link to Stack/Container

[MPM-Marvin]

Is your feature request related to a problem? Please describe

When using Portainer for a Local server, or a External Server with Reverse Proxy, often times you end up accessing your Containers via Web Browser. Right now you need to note that as Label if you want to have this documented inside the Stack.

Describe the solution you'd like

A Dedicated field inside the Stack (Could remain a specific Label for all intents and purposes), that then introduces some sort of "link" button on the Container. Perhaps a sixth button in the Quick Actions, or a "redirect" of the Ports Link that is already present. It could even replace the Ports entirely if it is configured on a container, seeing as you're most likely to use that instead of just the direct Port access.

Describe alternatives you've considered

I have so far recorded links in Labels, opening the container to copy them out, and paste them into the browser. (This is only really needed in multi-user instances, otherwise I'd just bookmark them or something, but for us as a Team its helpful to have them there for the record.)
