[unittest] Unable to run unittest locally

[Blueve]

Description

The README.md told that we can run unit tests locally by executing python2 setup.py test, but it will failed due to some packages are missing.

Is there a guideline to run the tests from scratch? Now, I have to enter sonic-buildimage repository and build the python-wheel to get a test result. Since the sonic-utilties is an independent repository and it has its own readme document, it is quite confusing me.

Expected Action For This Issue

Update README.md

Steps to reproduce the issue

1. Clone sonic-buildimage
2. Enter src\sonic-utilities
3. Run python2 setup.py test
4. Check the output

Describe the results you received

@jleveque , can you provide instructions in the README.md for how to run the unit test? It seems i heard multiple people have difficulty to run the sonic utilities unit test.

@Blueve, please try the instructions and let us know if you have any further issue.
