Exception when using `pip_index_url` with token

[robin-moss]

When using gitlabform I get the follow exception during it's version check (this check uses luddite)

http.client.InvalidURL: nonnumeric port: '[MASKED]@internal.repo'

We have two environment variables:

• PIP_INDEX_URL = https://username:password@internal.repo/repository/pypi/simple
• PIP_INDEX = https://username:password@internal.repo/repository/pypi/

It looks like the Python client __get_hostport is the cause of the error as it looks for a : and expects the right-hand side to be the port.

Full stack trace:
