    Don't define polling_interval option in two places

    The option is currently defined in two places - as a generic agent
    option and as a sriov agent specific one. This is a problem now that
    oslo.config tracks location where options are defined
    (I6dec1e09dcab203c6287f9c56c866f220a42f850) because when unit test
    runner imports all modules, it registers the option from those two
    separate locations, and since locations are different, it's considered
    the options are duplicate, which results in the following error:

    DuplicateOptError: duplicate option: polling_interval

    To fix the issue, I removed the definition of the option from sriov
    module and made sure the common agent options are registered whenever
    the sriov module is imported.
