Memoize SeedImage building

[agracey]

Currently, if I go to the UI and click "Build ISO" a new SeedImage gets created. If I keep clicking this button, I end up with a bunch of pods all hosting the same thing.

Would it make more sense to add some labels/annotations to that SeedImage CR then match the requested config to allow for reuse?

We somehow already do something that could be useful on the backend side: we have annotations tracking the base image, the referenced registration and the cloud init that would allow us to know if we should re-build the ISO or not on SeedImage update.
So, on the UI side keeping the same name for the seedimage (overwriting it if already present) may work 🤔

Could we move this to the ui repo? (I don't have the correct permissions)

Issue moved @agracey . I've asked for permissions to add the elemental group to the elemental-ui repo so that you could do this kind of operation (I don't have enough permissions to do that). 🙏

I'll have to check if that will work. Thanks for the input @fgiudici 🙏
