Function that creates and adds to the 'sys.meta_path' an HttpImporter object equipped with a URL of a Online Git server.
The 'url_builder' parameter is a function that accepts the username, repo and branch/commit, and creates a HTTP/S URL of a Git server. Compatible functions are '__create_github_url', '__create_bitbucket_url'.
The 'username' parameter defines the Github username which is the repository's owner.
The 'repo' parameter defines the name of the repo that contains the modules/packages to be imported.
The 'module' parameter is optional and is a list containing the modules/packages that are available in the chosen Github repository.
If it is not provided, it defaults to the repositories name, as it is common that the a Python repository at "github.com/someuser/somereponame" contains a module/package of "somereponame".
The 'branch' and 'commit' parameters cannot be both populated at the same call. They specify the branch (last commit) or specific commit, that should be served.
