Bad owner for vhost log directory

[randomstuff]

The vhost log directory is owned by root (and only root can write there):

# From Nginxpack::Vhost::Basic
file { "/var/log/nginx/${name}/":
    ensure => directory,
    mode   => '0770',
    owner  => 'root',
    group  => 'root',
}

However the log file should be writeable by www-data:

the user whose credentials are used by worker processes should have permissions to create files in a directory with such logs;

The result is a bunch of errors such as:

2017/09/06 06:32:23 [emerg] 6964#0: open() "/var/log/nginx/example/access.log" failed (13: Permission denied)

See issue #7 however.

Maybe we need in the logrotate snippet:

su www-data adm
