Modernize ludios_wpull

[HeliosLHC]

This is a continuation of the modernization efforts for ludios_wpull to support newer Python versions.

Python Version Change
Python 3.12 was selected due to a potential regression identified in Python 3.11.X

Wpull Version Change
This will raise the version from 3.0.9 to 5.0.0a (4.X.X is skipped per recommendation from @JustAnotherArchivist as my other internal fork of ludios_wpull is using it). The "a" is to denote this is an alpha-release.

Changes

• Bump version from 3.0.9 to 5.0.0a
• Replace deprecated setup.py with pyproject.toml
• Refactoring of deprecated async code to use modern asyncio (async/await) syntax
• Dependencies
  • Upgrade Tornado to version 6 and refactor code to support it
  • Upgrade SQLAlchemy to version 2 and refactor code to support it
  • Upgrade yapsy (master branch) to latest version to support Python 3.10+
    • Latest release version is very old and doesn't support newer Python versions
  • Add packaging dependency used by yapsy (does not recursively resolve)
• Change name written to WARC metadata from "Wpull" to "ludios_wpull" per @JustAnotherArchivist 's recommendation
• Unit Tests
  • Fixed the majority of the existing broken unit tests
  • Refactor unit tests to use modern asyncio, IsolatedAsyncioTestCase, and Tornado's gen_test where possible
  • Replace deprecated unit test assertion methods
• Tornado
  • Removed deprecated Tornado code
  • Replace custom ConcurrentHTTPServer with now native ThreadingHTTPServer
• Remove logic for handling older deprecated Python versions (below 3.7)
• Replace namedlist with dataclasses where possible
• Replaced deprecated sub classing of object and certain collection types
• Refactor certficate and SSL related code to support changed behaviors to Python's stdlib SSL library

Remaining Broken Unit Tests
These are unit tests that remain broken from the existing ludios_wpull version or will introduced

1. There are 1 remaining unit test that were broken on Python 3.8 and are still broken on Python 3.12 which is: Fix/remove wpull.proxy.proxy_test.TestProxySSL #8

2. There's a broken unit test related to how Python 3.11 or Python 3.12 changed socket re-use behavior. This impacts unit test: wpull.network.connection_test.TestConnection.test_sock_reuse

Todo

• Stabilize version 5.0.0a to make it to beta/RC and final release as 5.0.0 or higher.
• Upgrade grab-site
