[Api Integration] enhance of test/api_integration/apis/index_patterns tests

[alexwizp]

During execution of test/api_integration/apis/index_patterns integration tests I see a lot of errors in Kibana server console.

It happens cause all of that tests are based on not-existing ES index. To avoid this error before creating Kibana index you should load some data into ES using esArchiver service.

Example of using esArchiver you can find here: https://github.com/elastic/kibana/blob/60543b19de916f13f30164a0903eccd4f1de07ba/test/api_integration/apis/index_patterns/scripted_fields_crud/delete_scripted_field/errors.ts

Also all created Kibana indexes should be removed after the test suite has finished running. This does not happen for these tests:

Closing this because it's not planned to be resolved in the foreseeable future. It will be tracked in our Icebox and will be re-opened if our priorities change. Feel free to re-open if you think it should be melted sooner.
