scripts/lib: use tester v0.8.5

[gyuho]

Worker nodes logs aren't used for now, so disable.

@gyuho what do you mean by "worker nodes aren't used for now"? The MNG's worker nodes are indeed used to house Pods that are spun up in the integration tests...

[gyuho]

@jaypipes Meant to say worker nodes "logs" :)

[SaranBalaji90]

@gyuho worker nodes logs are useful while investigating failures. What's the harm in uploading these logs? Do we pay for these extra spaces somewhere?

[gyuho]

@SaranBalaji90 Currently, the tester tool only downloads to the local machine. Uploading config file and kubeconfig to S3 bucket is supported but upload all logging files aren't "yet". I can implement this feature in the next release.

Updated upstream to upload gzipped file

Nice! Running the tests now

[SaranBalaji90]

@gyuho what I meant to ask is, do we still upload kubelet logs? that's super useful for investigation.

[gyuho]

@SaranBalaji90 Yes. e.g. i-00a1505dc938f9296-kubelet.service.out.log is the kubelet logs from the instance i-00a1505dc938f9296

LGTM!
