[REVER-42] ServiceNow Integration

[makeplane]

To goal of this issue is to support ServiceNow as an integration within Revert APIs.

ServiceNow documentation: https://developer.servicenow.com/dev.do#!/learn/learning-plans/washingtondc/new_to_servicenow/app_store_learnv2_scripting_washingtondc_servicenow_apis

Next steps:

• Familiarise yourself with the ServiceNow APIs
• Understand how we store OAuth credentials within Revert and make changes such that we can allow our users to be able to make a connection with a ServiceNow account
• Create apis to get users , tickets from a connected ServiceNow account
• Create apis to create a ticket to a connected ServiceNow account
