Create a test for the datastream support of create-track command

[gizas]

Describe the feature:

This issue means to track the effort for the functionality introduced in https://github.com/elastic/rally/pull/1531/files

Notes:

• The test should be part of https://github.com/elastic/rally/blob/master/it/tracker_test.py
• The test should validate command with arguments like below: esrally create-track --track=test --target-hosts=test.rally.gizas.elastic-observability-ocp.elastic.dev:9200 --client-options="use_ssl:true,verify_certs:false,ca_certs:false,basic_auth_user:'elastic',basic_auth_password:'<>'" --datastreams=".ds-metrics-*" --output-path=~/tracks
• We need to find a waty to create a data-stream in our race setup in order to be available to simulate the functionality
