[installer]: create a configmap with a simplified installation manifest

[mrsimonemms]

Description

Uninstallation can be invoked by kubectl get configmaps gitpod-app -o jsonpath='{.data.app\.yaml}' | kubectl delete -f -

This also tidies up the sort function - it's gotten a bit bloated so it's doing about 3 different things. This separates out each part into individual parts (SOLID FTW)

Have also renamed the sorter.go file to display.go as it's not just sorting in there now, which might get confusing to new eyes

Related Issue(s)

Fixes #6290

How to test

Deploy a version of the app, uninstall using the above command

Release Notes

Create config map to allow uninstallation of app

LGTM

[csweichel]

for future reference: we need to reign this back in; not export this in the future. Having our own version of what's essentially runtime.Object doesn't bode well.

[mrsimonemms]

Yeah, agreed. I don't want this used for anything else
