Feature #11250: inheritance for environments on resource level instead of
module level

We have a staging environment that has only minor changes from production
(example: apt and dns modules contain small changes because they are in
geographically different places).
Obviously, we could use something like:
<pre>nameservers => environment ? {
staging => [123.1.2.3, 124.3.2.1]
production => [127.1.2.4, 125.7.3.1]
}
file { /etc/resolve.conf:
source => template://puppet/dns/resolve.conf
}</pre>
But I'm not a big fan of that, as it gets messy when the changes are larger.
Besides that, I like to think that sometime in the future I want to release our
module library to the public, which means I don't want them cluttered with 'if
$environment == ' statements.
The approach used now is that we have two modules in
$confdir/environments/$environment/modules. These modules however, are only
marginally different from their production versions (minor apt and dns
changes). Even so, the whol module needs to be duplicated, which brings with it
soem dangers.
What I would like to see is a possibility to have resource-level inheritance
instead of module-level inheritance. So if we're in environment X and I'm
including a class apt::repo::backports, autoloading check
$confdir/environments/X/modules/apt/manifests/repo/backports.pp only, the rest
of the apt module doesn't need to be there. That way, changes between different
environments stay small.
Not sure if it is clear, feel free to ask questions.
