[tanganyu1114]

i have find the reason of the bug ,but i don't know how to fix it ,please help me !
when the helm chart define a application in the spec.template.labels only use app.kubernetes.io/name and not app the key word, the swck crd javaagent will use /app-app.kubernets.io/name/ as the javaagent unique name，but the name cannot contianed '/' ,so it is bug
