[carmenlau]

Description

Currently skycli secret remove [SECRET_NAME] only remove the db reference but not the k8s secret, to make sure the deployed microservices won't be affected. We should cleanup the unreferenced secrets.

Idea 1: Setup a job in cluster to remove deleted and unreferenced secrets
Idea 2: Check and delete unreferenced secrets when stopping microservices and removing domains

Secret type need to be handled

• tls
• docker config json for image pull secret
• opaque
