TailLog returns cut log on local Minikube for sanity test and unmarshaling fails

[vsukhin]

Describe the bug When I run sanity test on local Minikube, the test is passed, but TailLog return cut log, that can't be unmarshalled

To Reproduce Steps to reproduce the behavior:

1. Run kubectl testkube run test sanity
2. Specify '-f -v api_uri=http://testkube-api-server:8088 -v test_api_uri=http://testkube-api-server:8088 -v test_type=postman/collection -v test_name=fill-me -v execution_name=fill-me'
3. See error ⨯ invalid character 'p' looking for beginning of value

Expected behavior Either to fix the bug, becuase output depends from the buffer size or better to switch to message queue approach for execution results
