This PR adds PSC DNS support to the Python connector, including recent fixes for error handling:

  • Update is_instance_dns_name regex to match /.sql(-\w+)?.goog$/ and exclude /.global.sql(-\w+)?.goog$/
  • Use specific error types/codes instead of checking error message strings for CNAME loops
  • Disable periodic resolution for immutable instance DNS names
  • Distinguish transient vs non-transient errors in monitored cache
