1) Moved Redis connection to class (now you can redefine it and implement custom logic of redis connection. For example sharding based on session key).
2) Disabled test_with_unix_url_config it doesnt work.
3) Added Redis server selection based on session key (if use REDIS_POOL).
4) Tests for redis connection reuse & redis server selection.
5) Added info to README.md
