[feature/aws_setup] Fix dependency on default VPC and avoid recreating ingress rule.

[snadorp]

1. The setup was depending on eiither classic VPC or default VPCs. If there is no default VPC Security groups cannot be easily filtered by group name. To be able to query them from the API a Filter needs to be constructed.

2. Ingress rules where not checked for existence, meaning a second run of the setup script would fail, this case has been covered by silently ignoring exactly this case, thus not failing the setup procedure.

Awesome! LGTM. I'll merge this and update preview artifacts after testing it on aws.
