Add an `--inactive` option to the
`bulk_add_orgs_and_org_courses` management
command, which causes the backfill to set
`active=False` on all rows created in the
Organization and OrganizationCourse tables.

This will lower the potential data
integrity risk to production systems
such as courses.edx.org.

Upgrade edx-organizations to 6.6.0
