…ation (#181605)

## Summary

#181683

This PR moves the existing Security Solution API integration tests from
`x-pack/test/api_integration/apis` to
`x-pack/test/security_solution_api_integration` and apply tags for each
scenario.
(x-pack/test/timeline is not included in this PR as this PR is already
big)

## Todo in the follow up PR:
move `x-pack/test/timeline` to
`x-pack/test/security_solution_api_integration` (as this PR is already
big)

## What to review?
1. Please review if the codeowner is assigned  correctly.
2. Please review if the test cases are still valid.

## How to run the tests: 

Here we use explore/hosts with trial license as an example:
```
cd ./x-pack/test/security_solution_api_integration
```


**Start ESS server:**
```
node ./scripts/index.js server explore trial_license_complete_tier hosts ess

```

When the server is started, open another terminal

```
cd ./x-pack/test/security_solution_api_integration

node ../../../scripts/functional_test_runner --config=test_suites/explore/hosts/trial_license_complete_tier/configs/ess.config.ts

```





**Start Serverless server:**
```
node ./scripts/index.js server explore trial_license_complete_tier hosts serverless

```

When the server is started, open another terminal

```
cd ./x-pack/test/security_solution_api_integration

node ../../../scripts/functional_test_runner --config=test_suites/explore/hosts/trial_license_complete_tier/configs/serverless.config.ts

```
