Update SQL query to find pending portfolios.

The query to find portfolios that are pending provisioning is updated to
check for:

- a portfolio state machine that has an UNSTARTED or one of the CREATED
  states

I left several TODOs to ensure that the orchestration functions
correctly for portfolio.
