Adds psutil to CI Build Script

[sampathweb]

psutil gets installed as part of general requirements.txt. But sometimes, it takes a while to install all dependencies and background log reader starts its job. When it happens, it causes the CI to fail since psutil is not yet installed. So, install psutil in the beginning so we don't have this failures that occur sometimes.
