Aliases + module.params

[Alex Stephen]

I'm in the process of writing an Ansible module. 

I've currently got an Ansible task that includes this piece of code:

```

...

allowed:

  - ip_protocol: 'tcp'

  - port: '22'

...

```

AnsibleModule looks something like this:

```

  AnsibleModule(

    argument_spec=dict(

         allowed=dict(type='list', elements='dict', options=dict(

             IPProtocol=dict(required=True, type='str', aliases=['ip_protocol']),

             ports=dict(type='list', elements='str')

          ))

    )

  )

```

(tldr; ip_protocol is an alias of IPProtocol).

I end up doing some work with module.params later on. I would expect module.params to look like this:

```

{

  allowed: [

     {

        IPProtocol: 'tcp',

        ports: '22'

     }

   ]

}

```

Instead, it looks like this:

```

{

  allowed: [

     {

        IPProtocol: 'tcp',

        ip_protocol: 'tcp',

        ports: '22'

     }

   ]

}

```

Is there a way to get a version of module.params that doesn't have each alias listed out in this way?
