    Replace binding:capabilities with binding:vif_details

    In addition to binding:vif_type, the neutron core plugin needs to
    supply various information to nova's VIF driver, such as VIF security
    details and PCI details when SR-IOV is being used. This information is
    read-only, requires admin privileges, and is not intended for normal
    users. Rather than add separate mechanisms throughout the stack for
    each such requirement, the binding:capabilities port attibute, which
    is a dictionary and is not currently not used by nova, is renamed to
    binding:vif_details to serve as a general-purpose mechanism for
    supplying binding-specific details to the VIF driver.

    This patch does not remove or replace the CAP_PORT_FILTER boolean
    previously used in binding:capabilities. A separate patch should
    implement the specific key/value pairs carried by binding:vif_details
    to implement VIF security. Another patch will implement the key/value
    pairs needed for SR-IOV.

    The ML2 plugin now allows the bound mechanism driver to supply the
    binding:vif_details dictionary content, instead of just the
    CAP_PORT_FILTER boolean previously carried by the binding:capabilities
    attribute.

    DocImpact: Need to update portbinding extension API, but no impact on
    user or administrator documentation.
