Enabled the vhost priority to be set.

Previously, the apache vhost priority was hard coded to '15'.
This does not allow the vhost priority to be managed, even with
$extra_params, due to apache looking for either default_vhost OR
priority.

Vendor any2array function to support stdlib 3.2

Many installations are pinned to stdlib 3.2. This change vendors
the any2arry function from stdlib 4 until Puppet Enterprise
catches up. At that point the vendored function will be removed.
