* Change iam_managed_policy to return snake case
Import module_utils.ec2 methods explicitly
* iam_managed_policy: tidy argument spec
Remove unnecessary specifications (`default=None`, `required=False`)
Use `required_if` to check for `policy` when `state` is `present`
* Provide exception handling in iam_managed_policy
Pretty much all AWS API calls can go wrong, and we should handle them.
Update line wrapping to improve readability of method calls
* Improve error handling when policy version limit exceeded
Better document policy version limit exceeded, and check
the error code to see that that's actually what happened
(rather than e.g. no permissions to add a new version)
* iam_managed_policy: better handle pagination and retry
This module can add, remove, update versions, and set default versions
of managed policies. It will cycle out old versions of policies if too
many are present. It will check and set the version of the policy that
matches the pased in policy document if one already exists.
