Fix clog longer than test duration

[kakaiu]

When injecting a clog in simulation, the goal is often to apply it before the test ends. However, if the clog duration is set equal to the test duration, the clog may persist after the workload completes, lasting longer than intended.

Code-Reviewer Section

The general pull request guidelines can be found here.

Please check each of the following things and check all boxes before accepting a PR.

• The PR has a description, explaining both the problem and the solution.
• The description mentions which forms of testing were done and the testing seems reasonable.
• Every function/class/actor that was touched is reasonably well documented.

For Release-Branches

If this PR is made against a release-branch, please also check the following:

• This change/bugfix is a cherry-pick from the next younger branch (younger release-branch or main if this is the youngest branch)
• There is a good reason why this PR needs to go into a release branch and this reason is documented (either in the description above or in a linked GitHub issue)

I do not put this into a method because whether using a shorten clogDuration depends on workload. There are some workloads use clogTlog which wants to clog a pair almost forever.

Please let me know if you have any preference. Thanks! @gxglass

testDuration = 200.0 in DcLag.toml, which doesn't seem to be very long. And after the test finishes, unclogAll() should remove the clogging.

Can you explain the failure you've seen?
