Add new
GOOGLE_MANAGED_KAFKA_AUTH_PRINCIPALenvironment variable for principal override. This allows users to provide the auth principal for credential types where it cannot be programmatically fetched.This allows the auth server to be used with BYOID credential types such as Workforce Identity Federation.
Also dropped 2 imports that are not used and added
requestswhich the auth library needs for fetching some BYOID tokens.Googlers see b/449376528#comment13 for more details.
