This introduces a new filter called the "external processing filter." It is intended to allow an external service to be able to operate as if it were part of the filter chain using a gRPC stream. It is intended to support a variety of use cases in which processing of HTTP requests and responses by an external service is desired.
A document that describes the filter can be found here:

The CdnLoopFilter implements an HTTP filter that detects and prevents
CDN loops using the RFC 8586 CDN-Loop header. The filter can be
configured with the CDN identifier to look for as well as the number
of times the CDN identifier can be seen before responding with an
error.

Description: router: Create InternalRedirectPolicy to capture all internal redirect related options and extend it with pluggable predicates similar to retry plugins. The previous_routes and whitelisted_routes predicate allow creating a DAG of routes for internal redirects. Each node in the DAG is a route. whitelisted_routes defines the edges of each node. previous_routes serves as visited status keeper for each of the edge. This prevents infinite loop, while allowing loop to exist in the DAG.
Risk Level: Medium
Testing: Unit tests. Integration tests.
Docs Changes: Updated HCM architecture overview page. Added toctree for the predicates.
Release Notes: Updated version history.

Currently the generic HTTP compressor filter isn't exposed to users
even though it's used internally by `envoy.filters.http.gzip` and can be
used by external filter extensions.
Expose the compressor's config API to users. For example the filter
can be configured as follows:
...
filter_chains:
filters:
- name: envoy.http_connection_manager
config:
http_filters:
- name: envoy.filters.http.compressor
config:
disable_on_etag_header: true
content_length: 100
content_type:
- text/html
- application/json
compressor_library:
name: envoy.filters.http.compressor.gzip
config:
memory_level: 3
window_bits: 10
compression_level: best
compression_strategy: rle
...
Multiple compressor filters using different compressor libraries,
e.g. gzip and brotli, can be stacked in one filter chain.

This filter transform HTTP requests to AWS Lambda invocations.
The filter supports pass-through only. Meaning, the request body
is passed to Lambda as is. Note: Lambda requires the request to be in
JSON format.
In a later iteration, we'll wrap the headers the body in a JSON string
before passing it to Lambda.
The filter requires the ARN of the Lambda function and supports
per-filter-config. When the per-filter configuration is used, the target
cluster must be tagged with specific metadata. This indicates to the
filter whether to process the request or to skip it.
Lambda supports two invocation modes:
- Synchronous (Request-Response)
- Asynchronous (Event)
This initial version of the filter supports the synchronous mode only.
In a later iteration I'll add support for the asynchronous (Event-based)
version.

This PR introduces a parallel v3 API reference documentation tree to the
existing v2 one.
The docs/root/api-v3/ tree was copied from docs/root/api-v2 and the
necessary package path fixups were made manually. As a result, the tree
largely resembles the v2 docs. Long term this is likely to evolve to
reflect the shape of the new extensions tree.
The message type, field and enum anchors are sed'ed to be distinct and
self-consistent inside api-v3/.
There were a number of API proto changes that were made to obtain a
successful Sphinx build:
* References to deprecated fields were replaced by references to the replacement field.
* clang-format line wrapping in protoxform was removed, this breaks RST in some v3 protos.
* Some packages (type/metadata/v2, data/cluster/v2alpha) were force upgraded to v3, to deal with references to types that are distinct in v2/v3. This is OK as these packages probably make sense to bump for v3, in general we're going to have to think about how to do this more
cleanly, supporting dual v2/v3 references alongside each other.
* Some evil hacks for field renaming added to migrate.py for RouteAction.
There's also some additional machinery added to compute distinct v3/v3
build targets to point protodoc at.
Risk level: Low
Testing: Docs build, manual inspection.

This patch introduces a new checker, tools/api/validate_structure.py, that is run as part of the
bazel.api CI job. It ensures that the package layout for the API doesn't violate some constraints,
largely reflecting the heuristics we used for v3alpha migration.
Along the way, I discovered there were some packages that were versionless and not boosted to
v3alpha, and there were some extensions left behind in envoy.config. These are fixed as well to
allow the validation to succeed.
