:black_nib: Description

Fixed

• fbuffer: checks if key exists and is a SET (not a LIST) before potentially cleaning it at startup
• Redis Manager: TestIsManager(ip, port) logic was inverted
• Tests: check_start_stop did not check if filter is running properly

Added

• Alert Manager: possibility to connect to Redis via IP:port
• fbuffer/fconnection/fend/fsession/ftanomaly/ftest: possibility to connect to Redis via IP:port

TODO

• update documentation
• add tests for Redis through IP (at least in base tests)
