Change log collection fixture to put all logs into archive

Browse source 
When collecting logs we dump all of the logs into a directory, because it is RAM-intensive
to keep entire set of logs in memory, especially in a large cluster.
And we attach logs to Allure not as individual files, but as single zip archive, because it
is more convenient to download, attach to bugs, etc.
