* Fix Teleport update reconciliation on `status` updates This pull request addresses the issue where the Teleport operator reconciliation runs every time the operator updates the `status` subresource. This continuous reconciliation has led to an infinite loop, causing millions of reconciliations per minute. When an error occurs, such as having invalid role properties, the Operator updates the status and returns an error, which should trigger a rescheduled reconciliation with exponential backoff. The problem arises because the operator failed to enforce a resource generation change, resulting in an immediate trigger of a new reconciliation when the `status` field is updated. This pull request modifies the operator to avoid updating subresources and only trigger updates when there is a change in resource generation. Special thanks to @strideynet for confirming my hypothesis and giving the solution!
