Added additional dummy data and modified existing dummy data for servicenow testing
Added additional testing for global and servicenow delta operations.
Added queries for old and all vulns since a scan. Modified repository to use newer data model version and access old/all vuln queries. Modified service to conditionally expect three prepare_action_tickets and action_tickets methods: create, update, and close (being the actions). Added addtional comments and more standards-based method comments.
Fixed minor issue in jira helper based on changes to ticket service.
Added prepare_update_tickets, prepare_close_tickets, update_tickets, and close_tickets functionality. Also modified the display of IP-based tickets to make viewing ticket details more easy in servicenow.
