Replace boulder tests with pebble (#9918)

Pebble 2.5.1 supports OCSP stapling, so we can finally replace all boulder tests/harnesses with the much simpler pebble setup. Closes #9898 * Remove unused `--acme-server` argument Since this argument is never set and always defaults to 'pebble', just remove it to simplify assumptions about which test server's being used. * Remove boulder option from integration tests Now that pebble supports all of our test cases, we can move off of the much more complicated boulder test harness. * pebble_artifacts: bump to latest pebble release * pebble_artifacts: fix download path * certbot-ci: unzip pebble assets * CI: rip out windows tests/jobs * tox.ini: rm outdated Windows comment Co-authored-by: Brad Warren <bmw@users.noreply.github.com> * ci: rm redundant integration test Co-authored-by: Brad Warren <bmw@users.noreply.github.com> * acme_server: raise error if proxy and http-01 port are both set * acme_server: rm vestigial preterimate commands stuff --------- Co-authored-by: Brad Warren <bmw@users.noreply.github.com>
