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?
