MarketingCloudSDK::TriggeredSend doesn't support client ID

[will-in-wi]

In an enterprise installation, you have to provide a client ID as part of the SOAP response. I subclassed it to fix the issue in my system:

class OurWorkingTriggeredSend < MarketingCloudSDK::TriggeredSend
  def send(client_id)
    if properties.is_a? Array
      tscall = []
      properties.each do |p|
        tscall.push(
          'TriggeredSendDefinition' => {
            'CustomerKey' => p['CustomerKey']
          },
          'Subscribers' => p['Subscribers'],
          'Attributes' => p['Attributes'],
          'Client' => { 'ID' => client_id }
        )
      end
    else
      tscall = { 'TriggeredSendDefinition' => properties, 'Subscribers' => @subscribers, 'Attributes' => @attributes, 'Client' => { 'ID' => client_id } }
    end
    client.soap_post 'TriggeredSend', tscall
  end
end

But I'm not sure how this would prefer to be fixed upstream. If you would give me any hints as to a preferred mechanism, I'll send a pull request.

Thanks!
