This reverts commit 4e0074f177622cf825c343b63db5d1b51b1ec9f4.

The commit also adds the phpinfo role for testing purposes.

I don't use that machine to do Arch stuff; no need to have its key here.

Suppress nginx's stdout/stderr because it's not possible to stop nginx
from logging to stderr once it has been enabled, and it's enabled by
default (via compilation option).

Move the error_log to the root context as it applies to more than http.

The logrotate setup installed by nginx doesn't actually rotate the text
log files we've been using.

planet and sources roles still install configs that use text log files.

This is currently only covered by playbooks/all-hosts-basic.yml
