Add Support for Zendesk Tickets

[Jonathan-Zollinger]

support the following ticket requests:

• List Tickets
• Count Tickets
• Show Ticket
• Show Multiple Tickets
• Create Ticket
• Create Many Tickets
• Update Ticket
• Update Many Tickets
• Mark Ticket as Spam and Suspend Requester
• Bulk Mark Tickets as Spam
• Merge Tickets into Target Ticket
• Ticket Related Information
• Delete Ticket
• Bulk Delete Tickets
• List Deleted Tickets
• Restore a Previously Deleted Ticket
• Restore Previously Deleted Tickets in Bulk
• Delete Ticket Permanently
• Delete Multiple Tickets Permanently
• List Collaborators for a Ticket
• List Followers for a Ticket
• List Email CCs for a Ticket
• List Ticket Incidents
• Autocomplete Problems

This is complete when docs are supplemented with example usage (both successful calls and failures), and tests validate Zendesk's documented behavior - successful calls and failures (i.e. the updateUserSegment endpoint returns a 200 error code and the userSegmentObject created, thus tests should validate this and nothing more).
