Add command to populate organisation table with agreement details

When we first started recording the details of the agreements that
were signed by organisations, we stored a copy of the signed agreement
in Google drive. Later, we switched to storing the details in the
database instead.

This adds a command which is designed to be run once and which updates
the database for the organisations which had the details of who accepted
the agreement and when stored in Google drive.
