Device Management at Application level

[MarianRaphael]

Description

Currently, devices are paired with an instance. The idea here is that a device is no longer assigned to an instance, but rather to an application.

User Story

As a FlowForge user who primarily works with Devices, I want the capability to assign my Devices directly to an Application, So that I can better manage and utilize my resources without the need for unnecessary instance creation.

Discussed with @MarianRaphael - explore older idea that "Instances" is a single concept, some are local to FF, some are remote (what we now call Devices). Management all consistently at the Application level - what does that UX look like?

Any specific pieces here @robmarcer? This Epic, and the tasks listed are mostly implemented already. You can manage devices at the application-level, without the need for Instances

I was just checking all issues which are tagged as 'customer request' had a link to the relevant people. As far as I know we have now implemented everything the linked customer needed and we did so several weeks, possibly months ago but I didn't want to miss anything. I suggest I untag it as the customer is happy with what was delivered, OK?

Tagging the relevant stories, scoped to what they asked for is the better, longer-term play, rather than the high-level epic. Okay to keep the tag on here though
