    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.
    The authentication properties are:
        "discovery.sendtargets.auth.authmethod",
        "discovery.sendtargets.auth.username",
        "discovery.sendtargets.auth.password"
    Cinder Storage driver need to send discovery auth properties in this case,
    and the properties are:
        iscsi_properties['discovery_auth_method']
        iscsi_properties['discovery_auth_username']
        iscsi_properties['discovery_auth_password']

    (cherry picked from commit 45227bbbfd06d16e85e973e14ee8c30e267e8b42)
