Description

We create deployment use the pod selector directly from labels, which is not necessary and may cause problem when some user label value have changed (may be by third-party system). This may lead to dangling pod or service can not select pods. 

I suggest to use minimal and stable flink internal selectors to select the JobManager pod like app=xxx, component=jobmanager and service, taskmanager pod and so on.
