We were observed the situation, where pod has been created, triggered KuryrPort CRD creation and removed just before Kuryrport on_present event was handled, resulting in errors from KuryrPort side. Idea is to set the finalizer to the pod as quickly as possible, so that it wont disappear before we correctly set up the CRD. Change-Id: Iac82bb05a465e94e47356c3c873e11f00e5d0cd9
