Configurable feedback buttons in Rainbow client

When Rainbow is used as an output for alarm messages (e.g. from OTNS or IQ Messenger), it would be very useful if the user(s) could respond, for example to acknowledge or reject an alarm message.

When sending alarm message, the message broker usually must guarantee delivery. Therefore, it must know if and who responded to the message, to either stop delivery or escalate. This logic remains in the message broker.

In case of an alarm message, the value of the buttons could be ‘Accept’ and ‘Reject’. To make it more generic, perhaps the labels and values of the buttons could be made configurable, where the sending party sets the labels and possible response codes. Also, the option to show or hide a button should be an option, only to be used when needed.

Like:

<button1>
  <label>Accept</label>
  <response>value</response>
</button1>
