v2.4.0rc5

[abhinavsingh]

1. Added workflows to automatically publish containers to GHCR and DockerHub
2. Separate container releases for only proxy.py and proxy.py with openssl. Later is necessary when using TLS interception with containers
3. --local-executor is now enabled by default. To disable it, use --local-executor 0
4. Work now define a generic work interface. Previously tied to TcpClientConnection based work.
5. Added a proxy.http.responses utility. See methods now used throughout proxy.py for HTTP response packet generation. It also provides automatic compression based upon --min-compression-length flag.
6. Added TlsParser implementation. Will be used by UpstreamConnectionPool and elsewhere for SSL/TLS customizations/modifications
7. proxy.py now default listens on 127.0.0.1, not ::1. That is IPv4 is made default again. Issue is most linux system clients still fail with IPv6 out-of-box.
8. Added UpstreamConnectionPool lifecycle support within Work. Now every work has access to UpstreamConnectionPool which can be used to efficiently manage connections to upstream servers. UpstreamConnectionPool are currently managed one-per-cpu-core and not shared among all proxy.py acceptors.
9. Added message to HttpProtocolException based classes for helpful information without entire stacktrace.
10. Optimize HttpProtocolHandler pick of plugin for processing an incoming HTTP protocol based work. Underlying work implementations can then easily handle WEB_SERVER, HTTP_PROXY, SOCKS_PROXY sub-protocols. Previously, core used to iterate over all sub-protocol plugins and depend upon them to bail out if request doesn't match their sub-protocol specifications.
11. If no matching sub-protocol implementation exists, now HttpProtocolHandler returns BAD_REQUEST_RESPONSE. Previously in such scenario client connections would hang until timeout occurs.
12. Fixed a bug with PACFilePlugin when custom --pac-file-url-path was specified
13. Url class can now also parse authentication information from the raw urls.
14. Added ProgramNamePlugin
15. proxy.py now registers for SIGINT, SIGTERM signals and performs a clean shutdown. Previously, proxy.py acceptors could have been left running, even after the parent process terminates.
