## Summary

1. Apply #185870 for Security
Solution Explore and Investigation tests.
2. Remove duplicated tests.
3. Investigation/timeline/serverless tests are skipped atm.

How to run the api integration tests (Use Investigation Timeline ESS as
an example)
```
cd x-pack

node scripts/functional_tests_server.js --config ./test/security_solution_api_integration/test_suites/investigation/timeline/trial_license_complete_tier/configs/ess.config.ts

// After server is started, open another terminal

cd x-pack

node ../scripts/functional_test_runner --config=test/security_solution_api_integration/test_suites/investigation/timeline/trial_license_complete_tier/configs/ess.config.ts
```
