    Fix some plugins that don't check that nets + ports are owned by tenant

    bug 942713. This bug confuses the validate_networks() method of
    QuantumManager in Nova, causing it to believe that it is valid for a
    tenant to plug into a particular network when in fact that network is not
    owned by the tenant, nor the "provider".

    The patch also adds unit tests to confirm correct plugin behavior.

    This patch fixes the issue for the Sample Plugin, the OVS plugin,
    the Linux Bridge plugin, and the Ryu plugin, all of which has the
    same DB model. Validated the fix with the unit tests.

    I couldn't run the unit tests for the NVP plugin standalone, but by
    inspection, the code seems to handle this case. I wasn't able to run
    the Cisco plugin unit tests, and that code uses its own DB model, so I
    am uncertain whether this issue exists in that plugin.
