Codebase Refactoring for 2.0.0

[JamoDevNich]

Overview

Planning to tidy up the codebase and also take the opportunity to implement some new features 😀. The end goal is to enable the script to also function as a library (rather than only a CLI interface), and to improve maintainablility of the overall codebase.

The project will remain a single python file with no dependencies on external packages, and all of the existing functionality will remain.

Any suggestions/changes/feedback would be much appreciated!

Core Changes

• [x] Replace the 'web' function with Python's urllib
• [x] Create Session class to handle logging in/out & SNMP-over-HTTP requests
• [x] Refactor all classes to inherit a new base class ~'APIRequest'~ Edit: 'RouterSessionClientBase'
• [x] Create Output class to handle formatting the output in the command line
• [x] Custom session exceptions - e.g. login failed
• [ ] User input exception - allow an user to input text if running as CLI
• [ ] All global variables removed (except version)

Documentation

• [ ] Custom session exceptions
• [ ] User input exception

New Features and minor changes

• [ ] Check if a user is already logged in
• [ ] Add 'is ethernet/wlan' column to clients list
• [x] Include data from the base64-encoded login cookie to the diagnostic output
• [ ] Login action now returns HTTP status code 500 if the password is incorrect. Previously this used to be an empty response, could use this to provide a more user-friendly exception.
