[CI]: rewrite logs tests

[apostasie]

Commit 1 relaxes RunSigProxy refresh frequency.
Suspicion is that currently this is putting extra pressure on the runtime - especially for slow environments like EL.

Commit 2 rewrites all remaining logs tests with the new framework.

IMPORTANT NOTES:

• fix [CI]: TestLogsWithoutNewlineOrEOF flaky #4147
• some tests conditions have been made more stringent, since [LOGS]: nerdctl logs -f adds extraneous line feed #4201 got fixed
• tests are disabled for Windows - it seems like logging for Windows only works intermittently
• this rewrite does away with -d, as this is a significant source of flakyness - if this is not acceptable and we do believe that all these tests must be run with -d, let me know and I will come up with something else

Note that while torturing tests, the following issues showed-up:

• [LOGS]: logs are unreliable and randomly miss data #4243
• [LOGS]: on windows, logs do not show up / are extremely slow? #4237
• and to a lesser extent: [LOGS]: logs are lost when detaching #4233

Because of these, logs tests may/will fail randomly.

I have been sitting on this for a bit, as I couldn't make logs to work perfectly locally (see tickets), but I think it is time to merge and bring all logs tests to the new testing framework.

Worse case scenario, we flag them "flaky" and they go back to the retry bucket.
