Title: [RDS] VPC Security Group Support

This pull request merges in #1602 from @pchico and adds:

* Rename `vpc_security_groups_ids` -> `vpc_security_groups` for consistency with existing API
* Allow passing in EC2 SecurityGroup objects similar to how DBSecurityGroups work
* Documentation updates
* Unit tests for passing in both strings and SecurityGroup objects
