Allow to extend the supported products of mixlib-install

[Tensibai]

Signed-off-by: Tensibai [email protected]

Description

Mixlib-install doesn't have a native way to add supported products out of editing the product_matrix.rb file.
This make things complex to address Chef and other distribution install from the same tool (namely for cinc for what I'm insterested about).

This proposal allow to specify an extra file using the Product DSL to add products to the matrix with their own omnitruck url.

Pending conversation between @Tensibai and @ramereth to figure out best way forward.

Update for followers - @ramereth is gonna chat with @Tensibai this week so we can get this sorted.

OK, we have agreement on the approach here, but @Tensibai you need to rebase here...
