Use awx-plugins-shared code from awx_plugins.interfaces (#15566)

* Add `awx_plugins.interfaces` runtime dependency

* Use `awx_plugins.interfaces` for runtime detection

The original function name was `server_product_name()` but it didn't
really represent what it did. So it was renamed into
`detect_server_product_name()` in an attempt of disambiguation.

* Use `awx_plugins.interfaces` to map container path

The original function `to_container_path` has been renamed into
`get_incontainer_path()` to represent what it does better and make
the imports more obvious.

* Add license file for awx_plugins.interfaces
