ServiceNow incident integration should supply better metadata for alerts

The x_ibm_waiops_ai_manager_events table that is managed by the ServiceNow incident Integration has only a single field that links the alert to a resource.

This field is called "resource" and it contains the name of the resource.

There are no other fields available to assist in linking these alerts to CIs in ServiceNow.

Suggestions:

1. Include the uniqueId of the resource
2. Include a URL linking back to that specific resource (just like the x_ibm_waiops_watson_aiops table has a URL field that links to the incident and the x_ibm_waiops_ai_manager_events has a target_url field that links to the alert)
3. Allow the user to suggest additional field(s) from resources that should be sent to ServiceNow (as a JSON blob?)
4. Allow for a field that contains the cmdb_ci.sys_id field (for example if the ServiceNow Topology Observer is active)
5. Or, even better, have a cmdb_ci Ref field that is an actual link to the CI
6. Handle composite resources in a useful fashion. Currently only the name of ONE of the resources making up the composite is used, which may not be the name of a CMDB CI in ServiceNow if the resource is a composite even if one of the members of the composite came from ServiceNow.

Handling composites is tricky since even ServiceNow CIs might be merged into a composite, so which sys_id is appropriate. But right now there is not enough information to make anything more than a guess about which CI to link to.
