…art 2 (elastic#74815)

## Summary

This is the basics of end to end tests, so there could be a lot more, but this ties to cover the basics of the tests.

Test with:
```ts
node scripts/functional_tests --config x-pack/test/lists_api_integration/security_and_spaces/config.ts
```

Adds these tests for the route counter parts:
* create_exception_list_items.ts
* create_exception_lists.ts
* delete_exception_list_items.ts
* delete_exception_lists.ts
* find_exception_list_items.ts
* find_exception_lists.ts
* read_exception_list_items.ts
* read_exception_lists.ts
* update_exception_list_items.ts
* update_exception_lists.ts

Fixes a few minor strings, other tests, but no large bugs found with these tests
