Clean-up allure report output of the resource checking step

[ikalinin1]

Currently, resource checking results in a large amount of redundant data such as HTTP client logs, request/response attachments. See the report.
allure.zip

In order to simplify the step outputs and increase the user experience we need to refactor the report output of the step and reduce it to the resulting table.

Steps to reproduce:

1. run the tests https://github.com/ikalinin1/demo-tests
2. open report
3. go to RESOURCES suite and observe step representation in the report.

During the discussion with the team, we agreed, that it makes sense to store attachments with requests/responses.
At the same time to get rid of the information that duplicates in the final resource validation table, makes sense to get rid of the sub-steps for GET\HEAD reporting for resources (but should be present in the log) and leave them for pages. Example of the steps which may be removed on the screenshot:
