Add custom links to Operations->Environments buttons

Currently on the Operations->Environments page, we have controls for Open Live Environment, Deploy to... etc.

This is great, but in our organisation we also have a few other URLs that are related to the app in addition to the actual app landing page. These include Kibana logs, PagerDuty service, internal custom status page etc.

It would be great to be able to define these links from the jobs' Environments section, and be able to click through as I currently can for Open Live Environment.
