docs: Add values.schema.json and document the used values - #806

Conversation
This is mostly copied over from hive-operator since the file is not templated. Having a schema makes Helm validate values on install, upgrade, lint and template AND shows as a nice reference on ArtifactHub. One thing to note is that we include the "global" block even if it's not used by us. This is due to https://helm.sh/de/docs/chart_template_guide/subcharts_and_globals/ In short: When used as a subchart Helm injects a "global" into every subchart. If we don't declare it validation will fail when used as a subchart. This also documents all used values in values.yaml itself. NOTES.txt is not part of this since operator-templating#646 generates it.
