feat: importing existing clusters

[george-pogosyan]

It would be great, if everest could import existing cluster, created with percona's operators when installing in namespace.

@george-pogosyan it is something on our radar. I would appreciate if you can share more about your use case either here or we can jump into a call to discuss it. (feel free to book me here: https://scheduler.zoom.us/percona-sergey-pronin/30-mins)

What's blocking this, roughly? Trying to figure out if it would feasible trying to build a shim so we can manage pg-operator instances from Everest.

Hi @kylemclaren

I don't think anything specific is blocking this feature, we need to make sure the CRDs are compatible when "connecting" existing cluster to Everest and provide UI/API/CLI methods to perform this operation. I think the biggest effort will be to QA this feature for all 3 DB technologies we currently support. One of our priorities for Q1 2025 is ability to "import" databases to Everest from various sources like backups or "downtimeless" using DB replication. We need to discuss internally as another option "connecting" databases managed with operators to Everest.
