[Feature] possibility to check log contents

[camaeel]

Problem Statement

I would like to have a step to check pod log contents in automated and convenient way.

Solution Description

It would be great if podLogs could be used in try blocks, and checked for contents (just as command/script).

Alternatives

Workaround is to wait for workload to complete and check pod logs:

        - description: Check if pod logs contain information that the file was created.
          script:
            env:
              - name: namespace
                value: ($namespace)
            content:
              kubectl logs -n $namespace -l app=test-ebs-velero
            check:
              (contains($stdout, 'File /data/test.txt not exists. Creating')): true
