Setting username and password in the configuration URL does not work

[lvarin]

Describe the bug

Funnel (https://ohsu-comp-bio.github.io/funnel/docs/storage/ftp/) requires (for the moment) to add the username and password to any FTP URL sent in a task. If you do so, cwl-WES fails as interprets the username and password as part of the host.

To Reproduce
Steps to reproduce the behavior:

1. Go to cwl-wes' configuration, and set a FTP with the username and password embedded
2. Run any workflow
3. Check the task log and discover an error: socket.gaierror: [Errno -2] Name or service not known

Expected behavior

It should not fail, no explosions
