One can specify a MetadataKey with a path selector to pick up a host
from the dynamic metadata of the request or downstream. Selected
value can either be a string or a list with at least a single
element of string type. Request metadata is considered first.

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.

Commit Message:
With lots of clusters and route-tables in a cloud proxy, we are seeing tons of RAM been spent on stats while most of the stats are never inc-ed due to traffic pattern(or long tail). We are thinking that we can lazy init cluster stats() so that the RAM is only allocated when it's required.
To achieve that we need to have finer grained stats group, e.g. configUpdateStats() are frequently updated by config management server, while upstream_xxx are only required when there is traffic for the cluster, for this sub-group we can save RAM by lazy init it.
Introduce a new stats utility in this PR such that the nested StatsStruct is only instantiated when any of "->" or "*xx." operator is used.

Commit Message: application_logs: add bootstrap option to write logs in JSON format
Additional Description: Adds an option in bootstrap config to write application logs in JSON format, while supporting all the log-format flags as defined in the CLI --log-format option. Related to #25959 - this is the first step in the implementation for supporting custom JSON properties, while printing the application logs output in JSON format.
Risk Level: Low (all new code paths are only enabled by config option)
Testing: Unit tests

Aids in decorating access logs for requests that are subjected to ext_proc and fault calls. In ext_proc, the struct is copied into the filter state object that contains per grpc exchange stats. In fault case, it is copied into dynamicMetadata under the namespace matching the filter config name.

Commit Message: [ZK filter] emit fast/slow response metrics for error budget SLI calculation
Additional Description: Emit fast/slow response counter metrics for each opcode used for error budget SLI calculation.
Risk Level: low
Testing: unit tests
Docs Changes: This diff will update these two docs ZooKeeper proxy introduction doc and ZooKeeper proxy proto doc.
Release Notes: [ZK filter] emit fast/slow response metrics for error budget SLI calculation
Platform Specific Features: N/A
API Considerations: Did not find a good way to make repeated message unique (LatencyThreshold in this case) with proto validation. Also found that enum cannot be the key of the proto map.
