use node-red dropbox official

[craigmulligan]

I was experimenting with the dropbox node that node-red maintains and it appears to do everything we need as described in Agile-IoT/Architecture#5.

I think we should just install this directly in our agile-node-red until we have to fork to support idm.

What does everyone think?

@craig-mulligan , of course you can use an existent node. Could you explain here how it handles the OAuth2 authentication?

[craigmulligan]

It doesn't use OAuth2, when creating an app you can generate a third-party token. The node uses this + you app key to authenticate. You supply this info to form on the node.

We should check what we actually install in the stack

[rosogon]

@cskiraly : It is not installed for the moment.

@craig-mulligan , please modify https://github.com/Agile-IoT/agile-nodered/blob/master/Dockerfile to install the dropbox node on nodered.
