Title: Fixed #675: Added an ENV/Option to Configure USE_SIGV4

Currently the new AWS SIGNATURE V4 wasn't supported by the docker_registry.
I created a ENV Variable called AWS_USE_SIGV4 which can either be true or false.
This could also be set using the Configuration S3_USE_SIGV4 inside a config file
