Change -subj value passed to OpenSSL to comply with newer
versions (similar to a52c56e).
Switch order of the country and domain inputs.
Both changes are to avoid the "Something went wrong" error.
The cryptography package has created all sorts of installation trouble over the last few years, probably because of mismatches between OS-installed packages and pip-installed packages. Using a virtualenv for all Python packages used by the management daemon should make sure everything is consistent.
See #1298, see #1264.
The PHP5 packages have a dependency on (apache2 or php5-cgi or php5-fpm), and since removing php5-fpm apache2 started getting installed during setup, which caused a conflict with nginx of course.

* [Issue #1159] Remove any +tag name in email alias before checking privileges
* Move priprivileged email check after the conversion to unicode so only IDNA serves as input
* Install PHP7 via a PPA, enable unattended upgrades for the PPA, and switch all of our PHP configuration to the PHP7 install.
* Keep installing PHP5 for ownCloud/Nextcloud packages because we need it to possibly run transitional updates to ownCloud/Nextcloud versions less than 12. But replace PHP5 packages with PHP7 packages elsewhere.
* Update to Nextcloud 12 which requires PHP7, with a transitional upgrade to Nextcloud 11.0.3.
* Disable TLS cert validation by Roundcube when connecting to localhost IMAP and SMTP. Validation became the default in PHP7 but we don't necessarily have a (non-self-)signed certificate and it definitely isn't valid for the IP address 127.0.0.1.
