Integrate RLS based consent filtering with lake create and post-processing.

Added to lake creation is:

* Creation of OptOutConsent and LinkActPcpr tables.
* Creation of research schema and user.

Added to lake post processing is:

* lake/postprocessing/runner.sh that will loop post processing
* lake/postprocessing/runner.sql runs the SQL scripts in order.

  runner.sql runs in serializable isolation level, since the last command is to
  remove all rows from stream.append_id, and we do not want to delete rows that
  have been committed (added) to append_id since the transaction start,
  i.e. rows that were added to stream.append_id while executing the post
  processing based on a different snapshot of stream.append_id.

* lake/postprocessing/010/020 etc.

  New scripts are 020_opt_out_consent.sql to populate OptOutConsent.
  030_map_acts_to_pcpr.sql to populate LinkActPcpr.
