This updates the retry logic for API calls made by the connector:

Attempts to get an authentication token from the Google auth API are always retried 5 times.
SQL Admin API requests are retried up to 5 times if the http response status code is a 5xx. Otherwise they are fatal on the first error.

This also implements the exponential backoff logic defined used in the go connector. See: https://github.com/GoogleCloudPlatform/cloud-sql-go-connector/pull/781

This should be a "feature" -- it will have a noticeable usability change.
