Hey @adiralashiva8 ,

First of all - this is an awesome tool!

Here is a PR to replace Flask with Fast API along with few refactoring and optimizations
Closes #8

Change log:

Enhancements:

• Replaced Flask with FastAPI
• Serves static content on /static http path (using aiofiles and jinja2 templates)
• All routes are moved to a routes.py, this makes the main app.py easy to read and understand.
• Added a dal mysql adaptor for mysql db interactions. This avoids redundant code for connection object from being added.
• MySql connection object can be created with various predefined connection arg params as a dict
• Added support for managing configuration object through out applications
• Swagger support with FastAPI inbuilt
• Added a docker-compose.yml to local building of mysql in docker container and testing.

Refactoring

• Changes to html and static assets for relative paths since static content will now be served on /static .
• Mysql
  • Replaced with mysql-connector-python.
  • Connection object usage in all modules.
  • Adjusted mysql queries for syntax changes.
• Adjusted all routes to FastAPI standards/syntax.
• Refactored other modules to follow the changes above.
• Updated setup.py with version and dependency packages information.
• Updated README.md with latest instructions and information.

### Note: Changes are tested with MySql version 5.7

PS: The UI for rfhistoric remains the same, below swagger is a nice default addition by FastAPI
