Jenkins ElectricFlow Plugin globally and unconditionally disabled SSL/TLS certificate validation

CloudBees CD Plugin unconditionally disabled SSL/TLS certificate validation for the entire Jenkins controller JVM during the deployment/publication of an application.

CloudBees CD Plugin no longer does that. Instead, the existing opt-in option to ignore SSL/TLS errors is used during deployment for the specific connection.

This issue was caused by an incomplete fix for SECURITY-937.
