initial thoughts?

The point is to provide tools to allow processing of ansible module output so that dependant modules can take the output as input.  This improves composability of modules.

For example

```
    - name: Create scaling policies
      ec2_scaling_policy:
        state: "{{ item.state }}"
        profile: "{{ item.profile }}"
        region: "{{ item.region }}"
        name: "{{ item.name }}"
        adjustment_type: "{{ item.adjustment_type }}"
        asg_name: "{{ item.asg_name }}"
        scaling_adjustment: "{{ item.scaling_adjustment }}"
        min_adjustment_step: "{{ item.min_adjustment_step }}"
        cooldown: "{{ item.cooldown }}"
      with_items: asg_policies
      register: created_policies

    - name: Apply function to policy data
      util_functions:
        function: 'zip_to_dict'
        input: "{{ created_policies.results }}"
        args:
          - "name"
          - "arn"
      register: policy_data
  
    - name: Create metric alarms
      ec2_metric_alarm:
        state: "{{ item.state }}"
        region: "{{ aws_region }}"
        name: "{{ item.name }}"
        metric: "{{ item.metric }}"
        namespace: "{{ item.namespace }}"
        statistic: "{{ item.statistic }}"
        comparison: "{{ item.comparison }}"
        threshold: "{{ item.threshold }}"
        period: "{{ item.period }}"
        evaluation_periods: "{{ item.evaluation_periods }}"
        unit: "{{ item.unit }}"
        description: "{{ item.description }}"
        dimensions: "{{ item.dimensions }}"
        alarm_actions: "{{ policy_data.function_output[item.target_policy] }}"
      with_items: asg_alarms 
```
