Add module search path with Ansible 2.x API

Hi list,

I have a custom python module A that imports another custom module B. In Ansible pre 2.x API I was able to do something like

ansible.utils.plugins.action_loader.add_package(my.custom.package.B)

to add the package. What would be the best way to do that with the 2.x API.

cheers,
Evelio
