- added pyrightconfig.json with typeCheckingMode=strict - added type hints to all files except api.py - added type stubs for dns, etcd, consul, kazoo, pysyncobj and other modules - added type stubs for psycopg2 and urllib3 with some little fixes - fixes most of the issues reported by pyright - remaining issues will be addressed later, along with enabling CI linting task
