Add 'host' name to initialize/terminate volume connection

[Nirmal Ranganathan]

The volume connector information currently has {'ip', 'initiator'}. Some drivers require a hostname or a host identifier for the initialize and terminate compute-volume connections.

It should instead have {'ip', 'initiator', 'host'} and update the HpSanIscsiDriver to use the new connection information to assign/unassign the volume to a specific host.

    Updated HpSanISCSIDriver to use initialize/terminate methods.

    This is based on Nirmal Ranganathan's patch for Nova-volume, which
    added a new key 'host' for initialize/terminate volume connection
    information in nova to fix bug 992729.

    HpSanISCSIDriver should adopt the change in order to work properly.
    Also added missing unit tests for the HpSanISCSIDriver.

    Fixes bug 992729.
