gcp-auth-extension

Is your feature request related to a problem? Please describe.

Description

The GCP Auth extension currently reads properties manually using System.getenv and System.getProperty. The extension should instead rely on reading the configuration from ConfigProperties instead to ensure it is supported by declarative config.

Describe the solution you'd like

The auth extension's implementation leverages OpenTelemetry ConfigProperties for configuration.
