Backport #20967
Currently, it's impossible to connect to self-signed TLS encrypted redis instances. The problem lies in inproper error handling, when building redis tls options - only invalid booleans are allowed to be used in
tlsConfigbuilder. The problem is, whenstrconv.ParseBool(...)returns error, it always defaults to false - meaning it's impossible to settlsOptions.InsecureSkipVerifyto true.Fixes #19213
