Tim Gross eda7be552c csi: add dynamicplugins registry to client state store (#7330)
In order to correctly fingerprint dynamic plugins on client restarts,
we need to persist a handle to the plugin (that is, connection info)
to the client state store.

The dynamic registry will sync automatically to the client state
whenever it receives a register/deregister call.
