Commit Message:
This commit adds CONNECT-UDP (RFC 9298) support. UdpConnPool is added to create a UDP socket for a new CONNECT-UDP request, and UDPUpstream is added to maintain the socket and other relevant data associated with UDP upstreams.
We added an integration test for the terminating CONNECT-UDP proxy, but not the forwarding proxy in this commit. We are going to add test cases to cover the forwarding proxy scenario in a subsequent commit.
Additional Description:
Risk Level: Medium, the feature can only be enabled by the new configuration added in this commit.
Testing: Integration test
Runtime guard: envoy.reloadable_features.enable_connect_udp_support
Release Notes: added support for CONNECT-UDP (RFC 9298). Can be disabled by setting runtime feature envoy.reloadable_features.enable_connect_udp_support to false.
