terraform: import existing resources into terraform

Although it's possible to import existing AWS resources
into a terraformstate object using 'terraform import',
we should try to bring over as many currently existing
resources to our terraform files as possible in order to
reduce chances of something being accidentally deleted
or overwritten as we try to add new resources.

This change moves the definitions for the provider and
backend out of the "ecr" terraform into "main", and then
imports some pre-existing security groups and their rules
as a starting point.
