Support for bundle python whl ( wheel ) files that are close sourced

[konduri]

Had an issue where I had to bundle a wheel file for a python package that was closed sources and not available on pypi.

Had to work around it by installing a local pypi server (https://pypi.org/project/pypiserver), and hosting the package with the local server.
Then added the package_name can be resolved by rosdep by adding it to a local source list, and doing a rosdep update

Then added the following command after running the local pypi server on 8080
colcon bundle --pip-args --extra-index-url http://localhost:8080/simple

That fixed the issue. Making a note here to see if can be simplified or to have record for folks who have similar issue.
