[Alert details page] Show alert related cases on the alert details page in summary fields section

[maryam-saeidi]

Summary

Based on a discussion with @maciejforcone, the idea is to add case links related to the alert in the summary fields section. In the future, Maciej said we will consider having a separate tab on the alert details page to show the details of related cases.

Cases in alert table	Place to show it on alert details page

Implementation

After discussing this ticket with @cnasikas, here is an idea about implementing this feature: (Related PR for inspiration)

1. Create a kbn-cases-hook package and put the useBulkGetCases hook in this package.
2. Create a case component (based on CasesCell in triggers_action_ui) in kbn-cases-components package and use useBulkGetCases to fetch related cases.
   • This component will look something like: <CasesListComp ids=[‘id-1’] />
   • Make sure to pass all the Kibana services in a separate props called dependencies (example)
