* Allow catching exceptions with is_boto3_error_code
* Replace from_code with is_boto3_error_code
* Return a type that will never be raised to support stricter type comparisons in Python 3+
* Use is_boto3_error_code in aws_eks_cluster
* Add duplicate-except to ignores when using is_boto3_error_code
* Add is_boto3_error_code to module development guideline docs

### Using is_boto3_error_code
To use `ansible.module_utils.aws.core.is_boto3_error_code` to catch a single
AWS error code, call it in place of `ClientError` in your except clauses. In
this case, *only* the `InvalidGroup.NotFound` error code will be caught here,
and any other error will be raised for handling elsewhere in the program.
