Include standard attributes ID in OVO dictionaries to improve the OVN revision numbers operation

[Rodolfo Alonso]

When a new object is created, updated or deleted, when using the OVN backend, an OVN revision number register is created. This "OVNRevisionNumbers" register includes the object standard attribute ID.

Instead of retrieving the standard attribute ID for each object, the OVO dictionary could contain this information.

    Add "standard_attr_id" to some OVO dictionaries

    Included standard attributes ID in some OVO dictionaries to improve
    the OVN revision numbers operation. Having this ID, there is no need
    to retrieve it from the database.

    The following OVOs have been updated:
    - port
    - network
    - subnet
    - security group
    - security group rule
    - router
