SASL EXTERNAL for s2s is not checking if certificate validation is disabled

Description

Certificate validation can be disabled for s2s. When doing SASL EXTERNAL certificates are used again to verify the identity of the remote server trying to connect. Therefore, we should check if certificate validation is disabled for those installations that are not using valid certificates.
