Xenial default configuration refers to PHP5, not PHP7; uses incorrect default php-fpm socket path as well

[Thomas Ward]

Given that we now are having php7.0 in Xenial, the default configuration for NGINX needs updated to match.

While not enabled by default, the default configurations have 'preset' items to make it easier to just 'enable' PHP support; this includes pointing to the socket file path for php5-fpm. Given we don't have php5-fpm anymore, we need to update this to match php7.0-fpm's defaults instead.

This does NOT add any new functionality, nor does it change any default configuration of feature-enablement; it is to address cases where users use the default configuration examples instead of setting site configurations up themselves, so that we don't have any bugs filed for 'PHP FPM settings in defaults are not valid!' issues.

This is a bugfix only upload; it does not modify any existing functionality nor does it bring any new features. It simply updates the configuration with regards to php7.0 existing and php5 not existing.

This did not make it in before FeatureFreeze due to my own mistake, and some timing delays which delayed 1.9.11 entering Ubuntu in the first place

Debdiff for the fix.

[Launchpad Janitor (janitor)]

This bug was fixed in the package nginx - 1.9.11-0ubuntu2

---------------
nginx (1.9.11-0ubuntu2) xenial; urgency=medium

  * This is a bug-fix only upload and does not include any new changes to
    features.
  * debian/conf/sites-available/default: Modify PHP 'default example' settings
    to account for php5 being replaced with php7.0 in Xenial. Also adapt the
    UNIX socket path for php7.0-fpm to be the one used by default in Xenial.
