CLI helper tool

This CLI helper tool gathers all log lines related to resource | req-id from particular folder with logs. All related resources and their IDs used in Tempest tests are stored in machine-readable YAML file with the following format:

<test identifier>:
  status: PASSED|FAILED
  resources:
    <openstack-service name (nova|neutron|glance|keystone)>:
       <resource-name (port|server|security-group|router)>:
       <request-id (req-xxxx) >:
         name: <resource name (test-port-mytest|test-vm-)>
         id/uuid: <resource id>
         request: <exact request>
        http:
           error: <if exists>
           status_code: <>

This machine-readable YAML file can be generated using report_parcer tool: https://gerrit.mcp.mirantis.com/plugins/gitiles/mcp/osccore-qa-testing-tools/+/refs/heads/master/tempest_tests_resources
