Remove disabling of existing loggers and deactivate redis-logs

Currently, existing loggers are generally disabled, as enabling them would lead to many unwanted redis-logs. This could be adapted such that only redis-logs are disabled.

Search the repository for the code that disables existing loggers and for references to redis-logs. Start by tracing how logging is configured, then verify that existing loggers remain enabled while redis-logs are suppressed. Done means unwanted redis-logs no longer appear without disabling unrelated loggers.
