    Failed to discovery when iscsi multipath and CHAP both enabled

    Storage server may be configured to protect target discovering phase with CHAP
    authentication, in this case existing discovery command will be failed in Nova
    when iscsi multipath enabled. Nova need these below discovery auth properties.
        "discovery.sendtargets.auth.authmethod",
        "discovery.sendtargets.auth.username",
        "discovery.sendtargets.auth.password"

    Cinder Storage driver need to send discovery auth properties to Nova in this
    case and the properties are:
       iscsi_properties['discovery_auth_method']
       iscsi_properties['discovery_auth_username']
       iscsi_properties['discovery_auth_password']

    This issue not just for IBM Storwize, but also other storage drivers who need
    CHAP authentication to do iscsi discover.
