NetApp drivers could use wrong flexvols

[Goutham Pacha Ravi]

When using NetApp drivers, all available flexvols on a datastore are being reported to the Cinder Scheduler. This allows Cinder volumes to be created on flexvols not designated for OpenStack.

    Fix use of wrong storage pools for NetApp Drivers

    When using NetApp drivers, all available flexvols on
    a datastore are being reported to the Cinder Scheduler
    as available storage pools. This allows Cinder volumes
    to be created on flexvols not designated for OpenStack.

    This commit fixes the problem by delimiting which pools are
    eligible for provisioning via a configuration parameter
    'netapp_pool_name_search_pattern'. This allows
    the Cinder drivers to operate against a restricted
    set of storage containers.
