Requirements doesn't list dependencies

[mrvn]

Trying to build I get the following test failures:

redfish (unittest.loader._FailedTest) ... ERROR
tests.discovery.test_discovery (unittest.loader._FailedTest) ... ERROR

The Requirements in README.rst should list dependencies:

• python3-requests-toolbelt
• python3-jsonpatch
• python3-jsonpath-rw

[mrvn]

Debian detects more dependencies: "python3-json-pointer, python3-jsonpath-rw, python3-requests, python3-requests-toolbelt, python3-requests-unixsocket".

Does installing the dependencies from requirements.txt (pip install -r requirements.txt) solve this? We can certainly update the readme to reflect that, but I'd also like to ensure requirements.txt has everything needed.

Are these Debian packages you need to install rather than pulling things via pip? Does pip install -r requirements.txt not pull everything you need?
