BZ-1124767: Setting appropriate defaults for new properties trustStrategy and hostnameVerification introduced in BZ-1062552.

These defaults are used when the property is loaded from the resource's
plug-in configuration. This is necessary to handle situations in where a
resource was already in inventory when the new plug-in is installed.
