Ubidots' HTTP nodes for Node-RED

[dsepulvedar]

It would ideal to have POST and GET nodes to handle this request to Ubidots in Node-RED. Simplifying the setup currently needed to integrate Ubidots with Node-RED.

Just as the MQTT nodes UI, user should be only prompted to enter token and device label for the POST node, while the GET will also prompt for the variable label.

Also, GET method should retrieve last value with it's corresponding timestamp and context.

Hey @dsepulvedar that's a great idea to also use HTTP to send and fetch values from the nodes. We'll be working on that for the next version of the library.

Instead of adding two more nodes I think it'd be good to have a dropdown in the same nodes where you can select the protocol that you wish to use to consume Ubidots' API; that way we don't have to deal with more nodes to do similar things.
