Change the Overload Manager API to extend the overload action state with non-binary values. This will allow future overload actions to take effect in response to increasing load, instead of to the existing inactive/active binary values. This PR also adds a range field to the overload trigger config, though no actions currently trigger on the 'scaling' state.
The existing behavior is preserved by replacing all places where OverloadActionState::Active was being used with OverloadActionState::saturated(). This is a minimal re-hashing of #11697 for ##11427.

Testing: ran unit and integration tests

Introduces UdpPacketWriter Interface that can be used to perform writes in Batched/PassThrough modes by using QuicGsoBatchWriter implementation from QUICHE extension.
**Additional Description:**
UDP GSO (Generic Segmentation Offload) was introduced in Linux at version 4.18. It allows batch-writing of multiple messages into a single payload and sending these messages along as a batch in a single sendmsg syscall.
Currently, Envoy performs the sending of messages using simple sendmsg implementation in pass-through mode, i.e. no support for batch writing. With this change, UdpListener can use UdpPacketWriter interface as a DefaultWriter or a GsoBatchWriter to perform pass-through or batched writes respectively.
Detailed description of the changes can be found in the design document, [here](https://docs.google.com/document/d/16ePbgkfrzQ6v-cOVMSnKDja3dUdZvX-mxT9jw29rx4g/edit?usp=sharing).
**Risk Level:** Low, not in use
**Testing:**
- Added udp_listener_impl_batched_writes_test, to verify that multiple packets of varying sizes are batched/flushed as per gso specifications while using UdpGsoBatchWriter.
- Modified existing tests, to verify that UdpDefaultWriter performs writes in pass-through mode.
- Ran all tests. All 677 tests passed successfully.

* added generic freamework for testing filters.
This is a fuzzer for testing network-layer(L3/L4) filters.
Now Envoy has 20 network-layer filters which will deal with raw bytes from untrusted networks and thus they are security-critical to some extent. The idea of this is to write a fuzzer which can be applied to different kinds of network filters(potentially cover all the filters), and when new filters are added to Envoy, we won't need to write dedicated fuzzers one by one to give them fuzz coverage.

Currently, the HDS specifier proto gives endpoint information organized by their locality and grouped by cluster. This information is retained when doing health checks, however when responding with health statuses from each endpoint locality and cluster information is dropped. This puts all endpoint information into a flat list when returning, making it the responsibility of the receiver to re-structure data by cluster and locality.
This change follows a similar format to the specifier coming into HDS, organizing it in the same way. The proposed changed adds consistency to how messages are flowing in and out of HDS.
Note that his PR only contains the protos changes, and does not include implementation. This is done to get approval from api-shepherds for the changes before continuing.

This PR implements fault injection for Redis; specifically delay and error faults (which themselves can have delays added). I chose not to implement a separate filter after discussing with Henry; we concluded that the faults we felt were useful didn't need many levels- just a delay on top of the original fault, if any. In addition, as the Redis protocol doesn't support headers that makes it a bit different again from Envoy's http fault injection.

This unifies HTTP/1.1 and HTTP/2 stream error on invalid messaging. Previously HTTP/1.1 defaulted permissive and HTTP/2 defaulted to strict. This defaults both to strict, resetting connections on invalid requests. This will have a major latency impact if downstream is sending a mix of valid and invalid requests over HTTP/1.1
Additional Description:
This change is runtime guarded per default behavioral change rules. It can also be reverted by setting the default to permissive (for prior HTTP/1 behvior) then overriding HTTP/2 to struct (for prior HTTP/2 behavior).
This works in conjunction with #11714, as the HTTP connection manager enforces the strictness, so the responses need to be sent via the HTTP connection manager to have strictness applied correctly.
