Description: This field is used to carry opaque and implementation
dependent information of the upstream endpoints. The information may
be used by management server for debugging purposes.
Example: Consider a requirement of per 'user' load stastics for
debugging. Envoy will embed user info into the metadata field for
every upstream endpoint it sends load to. This user information will
be used by management server for debugging.
Sample message:
message ClusterStats {
cluster_name = ...
message UpstreamLocalityStats {
locality = ...
message UpstreamEndpointStats {
address = "endpoint1"
metadata = { "user" : "alice"}
...
}
message UpstreamEndpointStats {
address = "endpoint1"
metadata = { "user" : "bob"}
...
}
message UpstreamEndpointStats {
address = "endpoint2"
metadata = { "user" : "alice"}
...
}
message UpstreamEndpointStats {
address = "endpoint3"
metadata = { "user" : "bob"}
...
}
}
}

The issue is due to on the crash of Envoy::Network::Utility::getAddressWithPort because of the invalid port_value. Added max constraint validate rule to the port_value field.
Risk Level: Low
Testing: Tested unit tests (bazel test //test/server/config_validation:config_fuzz_test), built and ran fuzzers with oss-fuzz.

This PR contains changes to implement feature requested in issue #3823
- Adding DropOverload in eds policy which can be used to specify
drop_percentage per category.
- Adding DroppedRequests in load_report which can report deliberately
dropped requests for each category.

This patch implements load_assigment field in CDS' Cluster.
This change specifically adds the implementation of the new load_assigment field
for clusters with discovery-type: STATIC, STRICT_DNS and LOGICAL_DNS.
While adding this load_assigment field implementation to Cluster,
this patch also allows specifying optional (active) health check config per specified upstream host.
Risk Level: medium
Testing: unit tests
Docs Changes:
This unhides docs for endpoint health check config
Release Notes: N/A
Fixes#439

This PR avoids a situation in which we were losing track of data plane requests as follows:
1. Management server asks Envoy to track load stats for cluster Foo in a LoadStatsResponse for a 10s period. Envoy resets stats for Foo.
2. After the 10s timer, Envoy responds with Foo's stats, resetting them.
3. Management server asks Envoy to track load stats for cluster Foo in a LoadStatsResponse for a 10s period. Envoy resets stats for Foo.
4. After the 10s timer, Envoy responds with Foo's stats, resetting them.
Between 2 and 3, any stats for Foo requests that arrive were previously unaccounted for. We resolve
this (in a relatively backward compatible way) by not making any protocol changes except to require
Envoy to not reset stats for already tracked clusters.
If we were to design LRS from scratch to avoid this, there are better approaches, e.g. making it a
periodic reporting service rather than request-response, but we probably already have a bunch of
existing users of LRS and don't want to break them.

adds the required visibility rules and delegates the rest to the generic
api_proto_library. I tested the change by doing the following without
getting errors.
./ci/run_envoy_docker.sh './ci/do_ci.sh docs'
I changed the BUILD files using the following commands.
/envoy/api$ find . -type f -name BUILD | xargs sed -i -e 's/api_proto_library(/api_proto_library_internal(/g'
envoy/api$ find . -type f -name BUILD | xargs sed -i -e 's/"api_proto_library"/"api_proto_library_internal"/g'

Add load_assignment field in Cluster
This patch introduces load_assigment field in CDS' Cluster. This is an API change only.
This is part of effort on breaking #3261 into multiple PRs.
Risk Level:
Low, since it is hidden.
Testing:
Build api and envoy-static without error
Docs Changes:
Add load_assignment in Cluster of cds.proto.

This provides an alternative health check port, if set it allows an
upstream host to have different health check address port.

Introduce the concept of locality weighted LB (as distinct from zone
aware LB) in the docs and a new field in Cluster, locality_weighted_lb,
for configuring this behavior.

There are several main changes in this PR:
Create envoy.api.v2.core packages to break circular dependencies from xDS on to subpackages on to base protos.
Create individual packages for each filter and add independent versioning to each filter.
Add visibility constraints to prevent formation of dependency cycles.
Add gogoproto annotations to improve go code generation.
After moving xDS service definitions and top-level resource protos back to envoy.core.api.v2, cycles were created, since the second-level definitions depend on base protobuf definitions, and are in turn included from xDS; however xDS and base definitions are in the same package.
The solution is to split the base protos into another package, envoy.api.v2.core. That eliminates dependency cycles (validated using go-control-plane).
Added a few gogoproto annotations to improve golang code generation.
