Refactor uninstallation process (#74)

Docs PR: https://github.com/netbirdio/docs/pull/457

Changes:
* Split kubernetes-operator Chart to operator only chart
(kubernetes-operator) and configuration chart (netbird-operator-config)
* Remove delete validation webhooks for non-needed resources
* Allow abandoning Groups when still linked to a resource for over a
minute after deletion
* Fix duplciate Network Resource retrying heavily
* Fix SetupKey creation duplication
* Skip deleting routing peer since deleting network automatically
deletes it anyway
