Description: Taking advantage of the new feature introduced in [#12035](https://github.com/envoyproxy/envoy/pull/12035), which introduced quick visibility for init managers to check unready targets, this pull request adds protobuf message for unready targets and enables admin to dump configs of unready targets. An example of config dump for listeners’ unready targets is given in this pull request.
Introduce ```InitDumpHandler``` with ```handlerInitDump``` method to help dump information of unready targets.
Add ```dumpUnreadyTargets``` function for ```init::manager```.

Simplified Profile Action to have a per-process limit rather than a per thread limit which simplifies disk-filling concerns.
We want to prevent the profiler from filling the disk, and using a per thread limit creates more complexity and profiles (i.e. for the "global" limit would be #threads * limit per thread vs limit per process. The former is harder to reason about.

Add a field to the current protobuf of ScopedRouteConfiguration to enable on demand scoped route table loading. The on demand scope route tables will be loaded lazily. The lazy loading feature of route table associated with scope is achieved by extending the current vhds on_demand filter to support lazy loading of RouteConfigurationscoped route discovery service.If a scoped route configuration is set to be loaded lazily, upon a http request using SRDS, when the corresponding route table of a scope is not found, post a callback to control plane, request the route table from the management server, after the route table has been initialized, continue the filter chain.

In order to support TLS in a health check connection, a TransportSocket proto must be matched to build the proper TLS connection factory. These are matched by the repeated field transport_socket_matches in the cluster proto, which HDS is currently leaving blank when building this proto. As a result, there is not way to specify a TLS transport socket or any transport socket listed in the docs.
This change adds the transport_socket_matches field to the HDS health check specifier, and adds it to the Cluster config generated by HDS, to support transport socket matches per-health check.
Risk Level: Low
Testing: HDS Unit tests and integration tests pass. Added unit test to test that the transport socket matcher receives the correct fields. Added two integration tests with a TLS configuration, one over HTTP and one over HTTP/2.
Docs Changes: Added comments about the new transport_socket_maches field in the HDS specifier proto.

Currently, the maglev hash algorithm default to table size to 65537.
It is the recommended size by a paper but it is better if the user
can set this value.
This patch introduces a new MaglevLbConfig that contains table
size of maglev.
So, now, the user can set the table size of maglev by their situation.

This patch introduces hash based routing functionality.
It is very similar to tcp's one.
Previously, the udp proxy does not support hash based routing.
So, even if the lb_policy is set, load balancing algorithms will
select a host randomly.
This patch may very useful if some packets should be routed to same host
continuously.

Currently, the health discovery service takes a specifier with information about which endpoints to perform health checks on, which already supports information about cluster structure and locality information. However, when when forming a response holding endpoint health information, all notion of cluster or locality is dropped and endpoint information is stored in a flat list. This is problematic when there are several endpoints with the same address or port but with a different locality, cluster, or path.
This PR uses the previous proto change in Issue #12153 which added support for grouping endpoint health information by their respective cluster and locality.
Risk Level: Low
Testing: Added a unit test in test/common/upstream/hds_test, which sends a specifier to HdsDelegate with several clusters, localties, and endpoints. It then verifies that the response holds the same structure. Existing integration tests were also changed to check for the new proto structure, specifically ones that already group several endpoints by differing clusters or localities.

Un-Reverts 048583b, with fix for high cpu consumption.
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 PR fixes the issue previously seen with redis fault injection where excessive cpu was used on connection creation.
Faults record metrics on the original request- and the delay fault adds extra latency which is included in the command latency for that request. Also, faults can apply only to certain commands.
Future work: Add several other faults, including cache misses and connection failures.

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.

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.
