TLS/SSL verification when using OpenShift provider

There was major refactoring of OpenShift provider in AntomicApp 0.3.0. In that version provider stopped using oc command and started using OpenShift API directly. In this version we permanently disabled TLS/SSL verification.

Now with 0.3.1 TLS/SSL verification is enabled by default and there are options that allow user to add CA certificate or disable verification completely.
