[Cases][Timeline] Saved Object Type Conversion

[jonathan-buttner]

As part of the effort to make saved objects shareable across multiple spaces we need to make a few changes to how Cases and Timeline interacts with the saved objects. This is required because in 8.0 the kibana core team is changing how the internal saved object id value is being stored to support being shared across multiple spaces.

The meta ticket for the core team is here: #100489.

The first thing is to migrate any of our foreign key fields (fields that reference another saved object's id field) to the references field. After this migration is complete we need to switch our usage of the saved object get API to use resolve instead as noted in the meta ticket above.

The tasks associated with this work are the following:

• Cases
  • Migrate connector IDs to references [Cases] Migrate Connector ID Fields to References #107561
  • Migrate connector IDs to references for cases user actions [Cases] Migrate Connector ID Fields to References #109177
  • Remove our usage of the saved object's .get API to .resolve and handle the 3 outcomes ([Cases][Sharable SOs] Use resolve for deep links #110854)
    • Adjust the UI as need to direct the user to the migrated saved object in 8.0
• Timeline
  • Migrate IDs to references ([Security Solution][Timeline] Migrate IDs to references #110863)
  • Switch to .resolve() ([Security Solution][Timeline][Sharable SOs] Use resolve for deep links #110862)

In case anyone is following this issue but not the linked meta-issue (#100489):

I published the Sharing Saved Objects developer guide, please take a look before proceeding with the implementation. And of course, please reach out if you run into any problems!

Heads up, I'm adding a new reference to the Kibana data view saved object (index-pattern) on the timeline saved object as part of this work https://github.com/elastic/security-team/issues/772
