* ec2_eip: (integration tests) move to using module_defaults
* ec2_eip: (integration tests) expand integration tests
Also clean up a little
- Delete EIPs when we finish testing them (reduce the chance of hitting limits)
- Rejig deletion so that it works when runs fail
- Add tests for ec2_eip_info
* ec2_eip: Minor doc tweaks
* ec2_eip: Don't throw an exception when we try to disassociate an already disassociated EIP
* ec2_eip: Add missing IAM policy (manage IGWs)
* ec2_eip: (integration tests) Use the VPC as a crude lock to avoid running parallel tests
We test that untagged EIPs come and go as we expect, if multiple tests are
running in parallel this confuses things
* Fix ec2_eip association
