Ability to setup Conditional Options using the API

[CCristev]

Hi,

With the recent addition of Conditional Options (https://knowledge.hubspot.com/properties/set-up-conditional-options-for-properties), we are now able to set up conditional options through the HubSpot interface.

However, at the moment, there's no easy way to set up conditional options through the API. And the process can be tedious for uses cases such as the Country <> State relationship, where a given country may have dozens of states to set up manually.

Therefore, could you please look into adding a new endpoint to the API?
