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"}
...
}
}
}
Risk Level: Low
Testing: Compiles successfully.

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 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.
Rist Level: Low
Testing: Modified load_stats_integration_test.

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.
