Update docs for the release of Consul API Gateway v0.5 (#15015) 

* added usage folder to organize use case docs for CAPIgw

* Add peer field to MeshService configuration page

* Add first pass at guide for routing to peered services

* Add exception to same-datacenter restriction for referenced Consul service

* Add example HTTPRoute referencing the MeshService as backendRef

* Add example ServiceResolver

* Add note about current ServiceResolver requirement

ServiceResolver may eventually be created implicitly by the API gateway controller, but that decision is pending.

* tweaks to the usage page for routing to peered services

* tweaks to the  description in the  configuration reference

* resolved TO-DOs from previous iteration

* Remove datacenter federation from limited support matrix

* added tolerations doc

* Remove note excluding k8s 1.24 since we now support it

* Reorder sections to maintain alphabetical sort

* Add example configuration for MeshService resource

* Adjust wording + indentation of other docs

* Use consistent "example-" prefix for resource names in example code

* reframed the tolerations documentation; STILL A WIP

* add helm chart documentation

* removed tolerations from gwcconfig configuration model reference

* Apply suggestions from code review

## Introduction
A `MeshService` is a resource in the Kubernetes cluster that enables Kubernetes configuration models, such as `HTTPRoute` and `TCPRoute`, to reference services that only exist in Consul. A `MeshService` represents a service in the Consul service mesh outside the Kubernetes cluster where Consul API Gateway is deployed. The service represented by the `MeshService` resource must be in the same Consul datacenter as the Kubernetes cluster.

A `MeshService` represents a service in the Consul service mesh outside the Kubernetes cluster where Consul API Gateway is deployed.
The service represented by the `MeshService` resource must either be in the same Consul datacenter as the Kubernetes cluster or imported from a peered Consul cluster.

# Reroute HTTP Requests
This topic describes how to configure Consul API Gateway to reroute HTTP requests.
## Requirements
1. Verify that the [requirements](/docs/api-gateway/tech-specs) have been met.
1. Verify that the Consul API Gateway CRDs and controller have been installed and applied. Refer to [Installation](/docs/api-gateway/install) for details.
## Configuration
Specify the following fields in your `Route` configuration. Refer to the [Route configuration reference](/docs/api-gateway/configuration/routes) for details about the parameters.
- [`rules.filters.type`](/docs/api-gateway/configuration/routes#rules-filters-type): Set this parameter to `URLRewrite` to instruct Consul API Gateway to rewrite the URL when specific conditions are met.
- [`rules.filters.urlRewrite`](/docs/api-gateway/configuration/routes#rules-filters-urlrewrite): Specify the `path` configuration.
- [`rules.filters.urlRewrite.path`](/docs/api-gateway/configuration/routes#rules-filters-urlrewrite-path): Contains the paths that incoming requests should be rewritten to based on the match conditions.
To configure the route to accept paths with or without a trailing slash, you must make two separate routes to handle each case.
### Example
In the following example, requests to` /incoming-request-prefix/` are forwarded to the `backendRef` as `/prefix-backend-receives/`. As a result, requests to `/incoming-request-prefix/request-path` are received by `backendRef` as `/prefix-backend-receives/request-path`.

# Route Traffic to Peered Services
This topic describes how to configure Consul API Gateway to route traffic to services connected to the mesh through a cluster peering connection.
## Requirements
1. Consul 1.14 or later
1. Verify that the [requirements](/docs/api-gateway/tech-specs) have been met.
1. Verify that the Consul API Gateway CRDs and controller have been installed and applied. Refer to [Installation](/docs/api-gateway/install) for details.
1. A peering connection must already be established between Consul clusters. Refer to [Cluster Peering on Kubernetes](/docs/connect/cluster-peering/k8s) for instructions.
1. The Consul service that you want to route traffic to must be exported to the cluster containing your `Gateway`. Refer to [Cluster Peering on Kubernetes](/docs/connect/cluster-peering/k8s) for instructions.
1. A `ServiceResolver` for the Consul service you want to route traffic to must be created in the cluster that contains your `Gateway`. Refer to [Service Resolver Configuration Entry](/docs/connect/config-entries/service-resolver) for instructions.
## Configuration
Specify the following fields in your `MeshService` configuration to use this feature. Refer to the [MeshService configuration reference](/docs/api-gateway/configuration/mesh) for details about the parameters.
- [`name`](/docs/api-gateway/configuration/meshservice#name)
- [`peer`](/docs/api-gateway/configuration/meshservice#peer)
## Example
In the following example, routes that use `example-mesh-service` as a backend are configured to send requests to the `echo` service exported by the peered Consul cluster `cluster-02`.
<CodeBlockConfig filename="serviceresolver.yaml">
```yaml hideClipboard
apiVersion: consul.hashicorp.com/v1alpha1
kind: ServiceResolver
metadata:
name: echo
spec:
redirect:
peer: cluster-02

kind: MeshService
metadata:
name: example-mesh-service
spec:

peer: cluster-02
```
</CodeBlockConfig>
After applying the `meshservice.yaml` configuration, an `HTTPRoute` may then reference `example-mesh-service` as its `backendRef`.

Learn about the changes to Consul API Gateway in version 0.5.x, including support for Consul Dataplane, routing to services in peered clusters, distroless Envoy containers, and Kubernetes tolerations

# Consul API Gateway 0.5.0
We are pleased to announce the following updates to Consul API Gateway.
## Release highlights
- **Consul Dataplane Support:** Consul 1.14 introduces a simplified deployment architecture that eliminates the need to deploy node-level Consul clients on Kubernetes. This is referred to as Consul Dataplane. API Gateway 0.5.0 supports this type of deployment.
- **Routing to Services in Peered Clusters:** API Gateway now supports the ability to route traffic to services that are imported from peered Consul clusters. Cluster peering is was added in Consul 1.14. Refer to the `MeshService` [documentation](/docs/api-gateway/configuration/meshservice) for additional information.
- **Deploy in Admin Partitions:** API Gateway can now be deployed in any Consul admin partition. Previous versions of API Gateway could only be deployed in the default partition. The partition is configured in the `GatewayClassConfig`.
- **Configure Maximum Incoming Connections:** You can now configure the number of concurrent incoming connections that Envoy will allow. This is configured by setting the value of the `maxConnection` parameter in the `GatewayClassConfig`.
- **Distroless Envoy Containers:** API Gateway now uses the `envoy-distroless` container image of the Envoy proxy. This improves the security of a gateway by reducing the attack surface of Envoy. Consul Helm chart `1.0.0` or greater is required to use the distroless container image.
- **Support for Kubernetes Tolerations:** You can now configure toleration settings for the Consul API Gateway controller and Gateway instances made with the managed gateway class directly from the [Helm chart](/docs/k8s/helm#h-apigateway). Kubernetes toleration settings allow you to control which nodes in a K8s cluster that the API Gateway pods should be deployed on. Refer to [Taints and Tolerations](https://kubernetes.io/docs/concepts/scheduling-eviction/taint-and-toleration/) in the Kubernetes documentation for more information.
