Bug Description

NEC Plugin ignores OFC (= OpenFlow Controller, which is backend of this plugin) errors while deleting resources (network and port) from OFC, and it could leave some unused resources on OFC. If OFC/OFC-driver generates id which is in remained resources on OFC when creating new one, OFC will fail to create it.

How easy to generate duplicated ids depend on OFC or OFC-driver, but we have to consider this situation. So we will make NEC Plugin keep logical resource which had OFC error while deleting, to make sure there is no orphan resource on OFC.

    Make NEC Plugin keep error resources

    NEC Plugin used to ignore OFC errors while deleting resources from OFC,
    and it could leave some unused resources on OFC. If OFC generates id
    which is in remained resources when creating new resource, it will fail.

    This commit makes NEC Plugin keep logical resource when it failed to
    delete resource from OFC not to leave orphan resource on OFC, and raise
    exception to tell the user that the resouce status is Error.

    NOTE: The user can retry deletion. If the resouce was successfully
    deleted from OFC in retries, the logical resource will be deleted.
