Re-enable Contacts syncing

[sminnee]

Contact data is a pretty important part of a data warehousing project and so its exclusion is a significant gap.

I see that the contacts API doesn't have an updated_since filter, but it looks like you could use the query API instead: https://developers.freshdesk.com/api/#filter_contacts

I believe that the following query would give you a data-efficient way of getting the data.

 /api/v2/search/contacts?query=updated_at:>(UTCDATE)

That sounds reasonable. Thanks for the info!

I'd also like to upvote enabling contacts-table-integration (but unfortunately I can't help technically).
