* Move profile and region checking to module_utils.ec2
Remove ProfileNotFound checking from individual modules
There are plenty of `if not region:` checks that could be removed,
once more thorough testing of this change has occured
The ec2_asg, iam_managed_policy and ec2_vpc_subnet_facts modules
would also benefit from this change but as they do not have tests
and are marked stableinterface, they do not get this change.
