cloud-sql-proxy v2

[kurtisvg]

Feature Description

This issue is tracking work on the next major version bump for the Cloud SQL proxy. V1 of this library has been around for over 5 years, and along the way both this library and the Go language have grown a lot. We think some of the improvements/changes we'd most like to see in the proxy may be impossible or severely more difficult without a major version bump.

Improvements

High Priority

• Separate dial functionality - Move "dial" functionality into a separate package/project #870
• Instance level metrics/tracing - Add support for metrics / tracing #169
• Explicitly defined public API
• Actionable Errors - More actionable errors #278

Medium Priority

• Default to listening on TCP port
• Per instance configuration for things like ipTypes and iam_login
• Find a replacement fuse library, or remove fuse support for MacOS - go.mod: pin old version of bazil.org/fuse #382

Low Priority

• Straightforward logging behavior to std out by default
• POSIX compliant flags

Anything we missed? Please feel free to chime in or provide feedback on anything you'd like to see (or not see).
