Deploy vhost template for nodepool.o.o logs

In Ie0b269835ebb8effbac0285b782d8add7b47db32 I didn't consider how
difficult it is to get puppet to put in AllowOverride directives to
allow .htaccess to work.  The puppetlabs-apache version we use does
not support "override" as an argument, so you can't easily add this to
allow apache to read htaccess.  Upgrading is a big task because we are
so far behind (see I6fa5f3275a84ec4480169de562d1d4a656111814).

So deploy a full template for nodepool vhost that includes the config
options we need.

Additionally, the existing mimetype isn't set for the log-files

I'm pretty sure this means it defaults to text/plain, but this makes
it explicit.  This should also matches on the timestampped log files
per the rules of multiple extensions [1]
