Add type field to store/policy json config

[binbin-li]

What would you like to be added?

When we configure store or policy through CRD, the metadata.name is the real name for this resource, and spec.name behaves as type. When we refactored verifier, verifier json config already supported both name and type fields so that users could set multiple verifiers of the same type.
We should also add type field to store and policy json config so that all resources have consistent behavior in CLI mode.

Anything else you would like to add?
