PSA: autopkgtest web servers

[Brian Murray]

The Ubuntu QA team has recently replaced the two apache web servers
which provide the autopkgtest web service with two machines with more
capable hardware which should make the web site more responsive.

Additionally, I've modified the servers to return a 403 status code if
one is trying to request a test and not logged in. This becomes
particularly useful if you pass the output of
retry-autopkgtest-regressions to curl instead of wget[1] e.g.

 $ ./retry-autopkgtest-regressions --log-regex "ERROR: testbed failure: cannot send to testbed" | vipe | xargs -rn1 -P10 curl --cookie ~/.cache/autopkgtest.cookie -o /dev/null --silent --head --write-out '%{url_effective}: %{http_code}\n'
https://autopkgtest.ubuntu.com/request.cgi?release=lunar&arch=s390x&package=node-imagemagick&trigger=graphicsmagick%2F1.4%2Breally1.3.38%2Bhg16870-1: 403
https://autopkgtest.ubuntu.com/request.cgi?release=lunar&arch=arm64&package=node-imagemagick&trigger=graphicsmagick%2F1.4%2Breally1.3.38%2Bhg16870-1: 200

Unfortunately, I'm getting a surprising number of 403s and that is being
tracked in a bug[1]. However, while we still need to sort out that bug I
wanted to pass along the information about using curl so that you can
tell more easily whether or not your test request was actually queued.
