[SIEM] Migrate to new platform

[spong]

This issue is for tracking the migration of the SIEM App to the Kibana New Platform. With the work done in re-bootstrapping the app for embeddables support, the only remaining Angular code is in mounting the SIEM App. Existing blockers are minimal and listed below. Intended timeline is to shim in 7.5, and migrate in 7.6 (blocker dependent). @XavierM and @spong will be leading the migration effort on the SIEM Team.

New Platform Migration Guide is located here.

SIEM App Blockers:

Client

• ui/autocomplete_providers (will likely replace with EuiSuggest Add Suggest component eui#2270)
• ui/index_patterns
• ui/vis/lib/timezone
• ui/documentation_links
• embeddable work-arounds that require hard refresh
• Filter service (new feature being worked on for 7.5, will use shim)
• ui/saved_objects/components/saved_object_finder
  • Fixed in Removing stateful saved object finder #52166
• ui/registry/feature_catalogue
  • migrated, but currently living outside the plugin due to timing issues, see cutover tasks
• Maps Embeddable Factory (uiExports/embeddableFactories)
  • [Uptime] New Platform Migration blocker #56332, [Maps][File upload] Migrate Maps embeddables to NP #58178
• ui/chrome
  • settings client
  • getBasePath
  • helpExtension
  • breadcrumbs
  • getXsrfToken

Server

• graphql hapi plugin (@rudolf follow-up with Jason’s / uptime’s work)
  Xsrf header
• indexPatternsServiceFactory (available as IndexPatternsFetcher https://github.com/elastic/kibana/pull/46537/files#diff-cbbf62a1e083f92fa02fc6ea4f392bacR39)
• KibanaVersion Available as PluginInitializerContext.env.packageInfo.version
• Actions plugin
• Alerting plugin
  • Migrate alerting plugin to New Platform #51652
• SavedObject Types Registration (Allow savedObjects types registration from NP #57430)

Cutover Tasks

These steps need to be done during the process of moving the plugin into new platform.

UI

• replace single usage of chrome.getKibanaVersion, swap with top-level config (via redux, if possible)
• move register_feature.ts into plugin (doesn't currently work due to manual plugin evaluation)
• follow up on [ui/utils/query_string]: Remove unused methods & migrate apps to querystring lib #56704
• wire up our config observable, ideally to redux

Server

• replace legacy config with observable value

For reference, client shim PR here: #48840

[rylnd]

#59624 was the 7.7 spike to get SIEM to NP; there were a few issues preventing that from being merged during 7.7, but it should be unblocked for 7.8.

@spong @rylnd The Maps embeddable was migrated last week in #58178, so SIEM should be completely unblocked from migrating the UI to the Kibana Platform. If there are any other blockers please let the Platform Team know!

[spong]

@rylnd just merged the client as part of #64251, so I think we're good to close this -- thanks for all the help along the way! 🙂
