    Force service provider relationships to load
    
    A race condition was exposed in the LBaaS V2 db layer that was caused by a
    hack to get around this issue.  The real issue is that since the
    ProviderResourceAssociation is inserted independently, any models that were
    created before this insert will not have their relationship with the
    ProviderResourceAssocation loaded.  Using the session.expire_all method will
    force the session to retrieve all new data and load this relationship for any
    resource that uses this relationship.
