Easier linking to applications in other clusters

[eggfriedrice]

Summary

It would be nice if applications list had easier links to other cluster consoles for applications on other clusters

Current Situation

At the moment you get a list with some greyed out applications names and this "Other cluster" warning:

Why do we need this? Who uses it, and when?

Anyone with applications in multiple clusters

Proposed Implementation

Make the "Other cluster" links clickable to go to the application in that other cluster. It might need a pop up warning or something, but it would be nice to be able to click, especially as the url for the target cluster is shown in the pop up help

Thanks @eggfriedrice for the issue.

This is possible for applications and for gateways where the LNS address is in a different cluster on the same deployment. We need some Regex to validate this and provide a link.
