HTTP/2 frames. When the limit is exceeded the connection is terminated.
This mitigates flood exploits where a client continually sends frames that

Promote tracing operation field to listener level. This expands the scope of the field to support two use cases:
Tracing TCP connections: istio can send connection events to create a service communication graph. Network filters can benefit from the common knowledge about the intent of the listener/filter chain (client-side vs server-side).
Using ingress/egress designation for other telemetry. The direction of the traffic is a useful label on metrics, and it is not explicit at the moment, unless depending on tracing configuration in HTTP connection manager or naming convention. Both workarounds are not ideal.

Due to a seg fault issue with the gogo protobuf library
[https://github.com/gogo/protobuf/issues/568], non nullable repeated
fields in a proto will cause proto.Merge(dst, src) to panic.
The nullable field setting was first added by @kyessenov when he was
re-organizing the protos. Unfortunately, people have been copy pasting it
across several areas in the Envoy proto. To keep the impact radius to a minimum,
I have updated only the fields that are currently causing the segfault
(in go-control-plane) for us.
Its also partly against proto principles. You should be able to determine if
a field is set or not. This non-nullable setting in gogo will insist on initializing
the field to default values.
Risk Level: to go control plane users

* grpc-json: add support for ignoring unknown query parameters
Current behavior is not to transcode a request that contains a query parameter
that cannot be mapped. In cases where there is a specific set of parameters to
ignore one can use ignored_query_parameters. If there is a proxy or client
adding query parameters that one cannot control this won't work and the
transcoder becomes useless. ignore_unknown_query_parameters solves this problem.
Risk Level: low to medium
Testing: Added a unit test for the transcoder.
Tested manually, locally.
Docs Changes:
Added field description in api/envoy/config/filter/http/transcoder/v2/transcoder.proto

Description:
this commit bumps protoc-gen-validate to the latest version. this
should unblock `wrowe` in slack working on windows support.
after this I believe we can also take use of the new address validation
type to fix some unique error messages, but the first step is bumping it
as a side note:
- SocketState was using `.message.required` however it was not
a message type. as far as I can tell this was a bug that PGV fixed.

Currently, in load_balancer_impl.cc: recalculatePerPriorityPanic(), even if common_lb_config.healthy_panic_threshold is 0%, a load balancer enters panic mode whenever normalized_total_availability is 0%.
I guess, a user who intentionally set to healthy_panic_threshold = 0 expects to immediately return error responses if there is no available host checked by a load balancer.
(In fact, current load_balancer_impl.cc: isGlobalPanic() decide not to enter panic mode whenever healthy_panic_threshold is 0%.)
So I suggest that panic mode is disabled only when healthy_panic_threshold is 0%.
I want this change for automatic degenerating lower priority or optional back-end services.
Risk Level: Low
(It seems that setting healthy_panic_threshold == 0 is a special case originally. It won't happen unless a user intend to disable panic mode, because default value of healthy_panic_threshold is 50%.)

Description:
Before this change, Envoy would silently ignore the `x-envoy-*` header if a
client specifies an invalid value for this header (e.g. `x-envoy-max-retries: 3.0`).
Introduce a `strict_check_headers` config option for `envoy.router` that adds
optional support to reject requests with invalid values for the following headers:
- x-envoy-upstream-rq-timeout-ms
- x-envoy-upstream-rq-per-try-timeout-ms
- x-envoy-max-retries
- x-envoy-retry-on
- x-envoy-retry-grpc-on
On rejection, Envoy responds with HTTP status 400 and sets a new response flag
`IH` to indicate the reason was due to an invalid header.
Risk Level: Low/medium
Testing: unit tests
- unit test: `FilterUtility::StrictHeaderChecker`
- test that router rejects request with HTTP status 400 + setting the `IH` response flag
- test that config validation rejects unsupported values
- manual end-to-end test `client -> envoy -> upstream server` to verify that
Envoy returns a 400 and sets the response flag in the logs
Docs Changes:
- add inline docs to `router.proto` for `strict_check_headers`
- add inline docs to `accesslog.proto` for `IH` response flag
Release Notes: updated for router and accesslog

This makes it possible to configure the subset LB to match metadata
match criterias with any of the values specified in a list value on an
endpoint. This allows endpoints to have multiple values for a given
metadata key.
To accomplish this the invariants of the subset trie construction
changed: a host can now be associated with multiple subsets for a set of
subset selectors. To support this the trie construction had to change to
traverse all possible paths for each host.
