Description of problem: In case a namespace is created-deleted-created, the last namespace creation event notices that a KuryrNet CRD still exists, as it can take a while for the previous deletion event to complete and will trigger again another deletion causing the following NotFound SubPort on Trunk error: namespace_subnet [-] Port d93da41a-4e9a-4140-ab08-a26bd10d775f is in DOWN status but still associated to a trunk. This should not happen.
