Question

The connectors in the other languages are structured with common names and separation of concerns.

Public API:

Connector is the main public API to configure and connect.
ConnectionOptions is the value object containing connection options. main public API to configure and connect.

Internal API:

ConnectorRegistry is the internal class that holds configuration and caches for each database instance.
ConnectionInfo is a value object that holds the configuration and data for one database instance.
ConnectionInfoCache interface holds the active ConnectionInfo value for a single database instance and keeps it up to date, refreshing the data as needed.
RefreshAheadCache implements the ConnectionInfoCache using the current connector refresh algorithm
LazyRefreshCache (to be added with #285) implements ConnectionInfoCache using the lazy refresh algorithm.
ConnectionInfoRepository calls the Cloud SQL Admin API to build an up-to-date ConnectionInfo object.

To get to the NodeJS connector codebase into state, we will need to move some code and rename some classes.
