Boostrap no longer creates an RDS database for a public mysql offering.

[#52483651]
Revert "Boostrap no longer creates an RDS database for a public mysql offering."

This reverts commit ea7a17091d4d5208ad11feb155427ae18022d443.

Requires a cross team pair. Also retro-actively changing a migration
that has already run is a no-no.
Merge branch 'master' into develop
