FibreChannelDriver doesn't implement validate_connector

[Walt Boring]

The base FibreChannelDriver doesn't implement the validate_connector() method. It falls back to the parent class which simply does a pass. The FC Driver should do a check on the connector and ensure that is has wwnns, wwpns to ensure that the child classes can actually do a volume attach. Without wwnns, wwpns, no FC driver can successfully do initialize_connection.

    Implement validate_connector in FibreChannelDriver

    The base FibreChannelDriver didn't implement the
    validate_connector() method. It fell back to the
    parent class which simply does a pass. Now the
    FCDriver checks to ensure that the connector has
    wwnns and wwpns and raises an exception if either
    one is empty or not set.
