Bump python version to 3.9 to address several vulnerability problems

FYI, I made these changes with the goal of addressing the issues shown in the vulnerability scan of the Docker image because, as per Amol's input, the vulnerabilities were related to libraries used in the python Docker image

Additionally, I removed some of the packages from the requirements file because they are already installed when Flask get installed because they are Flask's dependencies. Moreover, `dataclasses` got integrated into Python in version 3.7
