[RCA] Link dashboards and runbooks to the alert to use in investigation

[benakansara]

Discussion on slack

User should be able to link existing dashboards and runbooks in the rule form. When starting a new investigation from an alert, we can use this info from rule parameters to show dashboard links and runbook links on the investigation timeline. We would then save these links in investigation saved object.

Rule params / Investigation saved object

dashboards: [{
  id: string;
  name: string;
}],
runbooks: [{
  id: string;
  name: string;
  link: string;
}]

(Design to be updated)

Link dashboard

Link runbook

TBD
