uncloud-mravi/common/request.py
meow 6fa77bce4d Remove ucloud_common and put its files under ucloud.common subpackage.
Remove individual config.py used by every component and put them into single config.py ucloud/config.py
Use /etc/ucloud/ucloud.conf for Environment Variables
Refactoring and a lot of it
Make ucloud repo a package and different components of ucloud a subpackage for avoiding code duplication.
Improved logging.
