    Revert "Use HasStandardAttributes as parent class for Tags DB model"

    This reverts commit 85d3fff97e55ba85f72cda4365ad0441c10bd9f6.

    Reason for revert:
    The original change was made as a “cheap win” to optimize the number
    of queries the neutron server makes during testing. This did
    improve the number of queries made but introduced regression in
    real world deployments where some customers(through automation)
    would define hundreds of tags per port across a large deployment.
    I am proposing to revert this change in favor of the old “subquery”
    relation in order to fix this regression. In addition, I filed the
    Related-Bug #2069061 to investigate using `selectin` as the more
    appropriate long term solution.
