Add updated_at column and relevant tests, expand query functionality

[mtruj013]

Done

• Added updated_at column to CVE table to track time of update. On creation this field should default to the current time
• Expanded query functionality to include ability to filter by all text based fields
• Added 2 new parameters for CVE list get requests, and updated existing parameter
  • group_by: Groups CVEs by priority (critical -> unknown)
  • sort_by: Sorts CVEs by publish or update date
  • order: Orders CVEs by descending or ascending values. This param used to only accept "oldest" as a value and this usage will now be depreciated.
• Added tests for all of the above

QA

• See that tests are passing
