Copy/link existing FTR tests to test_serverless

[TinaHeiligers]

This issue may need to broken into sub-issues. We want to see how much test coverage can easily be ported over to the test_serverless folder. FTR tests of interest:

API integration

• test/api_integration/apis/core PR #167570
• test/api_integration/apis/saved_objects SO HTTP APIs removed in serverless
• (?) test/api_integration/apis/telemetry --> telemetry tests run for each Project type already
• test/server_integration/* not testing anything that could be a risk for serverless
• test/plugin_functional/test_suites/saved_objects_hidden_type SO HTTP APIs removed in serverless
• test/plugin_functional/test_suites/saved_objects_management (maybe API integration tests provide enough coverage and we can skip these?)
• [core] Add SOM api integration tests for serverless #175757
• test/health_gateway/tests Not used on serverless

E2E

• test/functional/apps/bundles
• x-pack/test/functional_execution_context/plugins/alerts
• (?) test/node_roles_functional/plugins/core_plugin_initializer_context

Other

• test/analytics/plugins/analytics_plugin_a
• x-pack/test/saved_objects_field_count
• test/analytics/tests
• test/plugin_functional/test_suites/core
• test/plugin_functional/test_suites/core_plugins

Pinging @elastic/kibana-core (Team:Core)

[TinaHeiligers]

@elastic/kibana-operations do you see any issues with us copying these tests to run for serverless testing?
@elastic/appex-sharedux is your team doing any of this work?

[Ikuni17]

@TinaHeiligers Some teams are reusing their tests, so it shouldn't be an issue. I haven't looked at your specific tests, but it may be necessary to setup tags to skip in specific environments. For example, if a test is flaky in serverless but not when running normally or if a test just doesn't work in serverless.

[TinaHeiligers]

@elastic/kibana-core it looks like we still need to do this work.
I'll get started with test/api_integration/apis/core. If other team members pitch in, we'll get through the list in the description more quickly.

If anyone does help out, please reference this issue in your PR(s) as partially addresses https://github.com/elastic/kibana/issues/167314

[TinaHeiligers]

@Ikuni17 I don't know how to use the tags. Where can I find out more?

[TinaHeiligers]

the first of many PR's borked, created a new one

[TinaHeiligers]

Reopening for other tests that need to be added.

[TinaHeiligers]

Adding the tests identified in the description would be faster if the whole core team worked on this, so I'm unassigning myself here.

[TinaHeiligers]

The original list as given in the description is stale. New issues will be opened for tests that need to be added.
