User prerequisites should be created when user is created.

[huxoll]

There are various entities that should be populated when an account is added to the system.

There are defaults for:
EC2 Security Group
DB Security Group
DB Parameter Group
Cache Parameter Group
Cache Security Group

etc...

We need to create these and handle them in a better way; rather than make spaghetti code where the CreateAccount action needs to know about all of them,
we should:
Create them as prototypes, and copy them per-user on edit
Create them per user, using a hibernate interceptor or the like to decouple account creation from services
