Add Association labels trough API/Workflow for Deals, Contacts, Companies, Tickets

[Janosch]

It would greatly allow the possibility of adding an association label through API or Workflow between HubSpot objects. 

Currently this is only available through the interface and in order to scalate the productivity of the company this would be a great feature.

I agree this is highly needed, as one contact can have several deals - for instance a contractor. I don't want the properties to be set on all of their deals, but just the one created through a particular workflow, for instance.
