This is currently just a spike of the feature for our consideration.
Work needs to be done to add tests and so on.
This adds support for Flipt using another Flipt instance as a backend.
In this mode, the replica Flipt will build an in-memory snapshot in the same way the declarative backends work.
This allows you to run one tier of Flipt to handle writes and the frontend, while deploying a fleet of read-only Flipts who serve evaluations from memory. This would support Flipt as a sidecar with fewer extra dependencies.
To achieve this, a new internal snapshot streaming RPC is added to send full snapshots to clients when state changes.
