Update python `requests` dependency

[acornett21]

The request dependency has had a CVE in it for awhile now, but the fixed version does not support http+unix protocol that is used in this project, so we cannot update.

This issue we would need to:

• See what it takes to update to new libraries/protocols
• Update requests library
• Address any testing gaps

More info in this comment and related slack thread.
