Teiid Importer *MUST* not require class-name property working with Teiid Sources

When working with "new" and "custom" translators in Teiid, the Teiid Importer fails to recognize the class-name property from the retrieved metadata. The following the excerpt from CLI command on a cassandra data source

        {"managedconnectionfactory-class" => {
            "type" => STRING,
            "display" => "managedconnectionfactory-class",
            "read-only" => "true",
            "advanced" => "true",
            "default" => "org.teiid.resource.adapter.cassandra.CassandraManagedConnectionFactory"
        }},

That property needs to be used as the "class-name", there must not be any hard coding of this to only known source types.
