Support ticket servicenow integration

[abujeda]

Added backend integration for Support Ticket with ServiceNow.

ServiceNow is a popular ITMS and Harvard IQSS is moving its OOD and cluster ticketing system to the ServiceNow platform.
This integration uses the ServiceNow API to create incidents from the support ticket form.

I will update the OOD documentation with the configuration settings once all is OK with the PR.

Sample configuration:

support_ticket:
  description: |
    This is a description text for the ServiceNow API
  attributes:
    subject:
      value: "OnDemand Problem: "
  servicenow_api:
    server: "https://dev251054.service-now.com"
    auth_token: "test-token"
    user: "ood"
    pass: "password"
    map:
      u_email_source: "email"
      watch_list: "cc"
    payload:
      contact_type: "External System"

Sorry I forgot to ask - do you need this backported to 4.1?

No, there is no need. We can use it as a customization until is available in a release.
Thanks
