If you apply `wait=yes` and use `instance_tags` as your filter for
stopping/starting EC2 instances, this stack trace happens:
```

That's because the `instance_ids` variable is None if not supplied
in the task. That means the instances that result from the instance_tags
query aren't going to be included in the wait loop. To fix this, a list
needs to be kept of instances with matching tags and that list needs to
be added to `instance_ids` before the wait loop.
Before this, all spot instance requests would fail because the code
_always_ called module.fail_json when the parameter was set (which it
always was, because the module parameter's default was set to 'stop').
As the comment said, this parameter doesn't make sense for spot
instances at all, so the error message was also misleading.
Due to a mixup of the group/role/user and policy names, policies with
the same name as the group/role/user they are attached to would never be
updated after creation. To fix that, we needed two changes to the logic
of policy comparison:
- Compare the new policy name to *all* matching policies, not just the
first in lexicographical order
- Compare the new policy name to the matching ones, not to the IAM
object the policy is attached to
The ssh_public_keys must be a list otherwise will give the error:
"argument ssh_public_keys is of type <type 'dict'> and we were unable to convert to list"
- Using set based comparison was not working consistently
- With != operator worked locally but consistently failed on Travis
- With 'not in' operator failed locally and on Travis
- Removed required_if.
- Fixed doc strings.
- Removed debug output being appended to actions.
- Put import of basics at bottom to be consistent with other docker modules
- Added 'containers' alias to 'connected' param
- Put facts in ansible_facts.ansible_docker_network
