The default instance has everything set to sensible defaults:
The default service address (iamcredentials.googleapis.com) and default port (443) are
used.
Credentials are acquired automatically through Application Default Credentials.
Retries are configured for idempotent methods but not for non-idempotent methods.
The builder of this class is recursive, so contained classes are themselves builders. When
build() is called, the tree of builders is called to create the complete settings object.
For example, to set the total timeout of generateAccessToken to 30 seconds:
// This snippet has been automatically generated and should be regarded as a code template only.
// It will require modifications to work:
// - It may require correct/in-range values for request initialization.
// - It may require specifying regional endpoints when creating the service client as shown in
// https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
