Description

@KlaudiuszRydzy found that some proxies were very large when serialized which ended up being specific to the LocalConnector storing it's data dict in the connector config.

This causes proxies to unexpectedly contain all the data in the connector because the proxy stores the connector config. This was useful for some specific tests, so that feature is now available under a flag.
