In preparation for Compass’s ability to persist OIDC tokens, we should add:

• A way to get an opaque serialized (string or Uint8Array) representation of a MongoDBOIDCPlugin’s instance (auth state only, not options or similar)
• The ability to take a “serialized state” string/blob, filter it, possibly by principal name, server metadata and/or expiration date, and then re-serialize that into a string/blob
• A way to pass such serialized state to a new MongoDBOIDCPlugin instance and then deserialize it
• An event that is emitted when the state that would be serialized changes
