We should adjust the benchmark to ignore jlap test setup/teardown. We should cache or save a local dummy ssl certificate used for that test https server.

I updated the documentation part of this PR to address @jezdez' comments. I think there is still value in the actual code changes; if you prefer not to add the deep dive, we can just remove that.

IMO we should remove initialize_root_logger, AFAIK this is the source of logging issues in downstream projects (e.g., conda/conda-build#5275 (comment)).

[zklaus]

I have simply removed initialize_root_logger. I think this is justified in light of the fact that the whole logging hierarchy starts with an additional "root", conda, which is configured separately.
