Issue:
Add support for specifying alt_stat_name for an upstream cluster
*Description*:
Add support for specifying **alt_stat_name** for an upstream cluster in the Envoy configuration. This would be extremely useful for better identifying services in observability.

Discussion:
@zirain: looks like [ClusterSettings](https://github.com/envoyproxy/gateway/blob/cc7104891d49d1c89b15f4b712ef055dbf4d65c9/api/v1alpha1/shared_types.go#L521) is a good place for this
@sekar-saravanan can you share more details about the user case@arkodg: can we auto populate this to a backendRef FQDN instead ?@sekar-saravanan: @zirain This is primarily for observability purposes. Currently, the envoy_cluster_name label provided by the EG metric appears as follows: _**httproute/seceng/gateway-dummy-service-external-origin/rule/0.**_ 
Supporting a configurable alt_stats_name would significantly improve the manageability and readability of metrics, making them more user-friendly.@github-actions: This issue has been automatically marked as stale because it has not had activity in the last 30 days.@guydc: If users control the prefix, they can decide to merge stats of various clusters when per-route-rule stat granularity is not required. This would also make it possible to better control scale of stats, which could be significant in EG, due to the way clusters are created. 

Auto-generating the alt_name (if user opts-in) would be a good option to reduce cardinality as well. I think that there are some questions, though:
- What should the alt_name be when a Backend with multiple FQDNs or no FQDNs is used? In this case, it might be better to use the resource's namespaced-name. 
- What should the alt_name be when multiple backends are referenced by a route rule? 
@guydc: Notes from community meeting with @arkodg, @zhaohuabing :
- User opt-in is required, as applying an alt_stat_name may lead to stats being merged across route rules and http routes, creating an incompatible change.  
- Auto-Generating an alt_stat_name based on namespaced-name of xRoute and BackendRef(s) reduces the scale of metrics and makes it easier to for users to search for metrics based on the service (as requested in this issue), instead of an anonymous indexed route rule. We may need to truncate the stat name if the list of backends is too long. 
- If we adopt weighted clusters, as mentioned in #5307, there would not be a need to collapse stats, as clusters would be created 1:1 with Backends/Services/ServiceImports. 

So, if a user attaches a BTP to a route and enables a new `statNameFromBackends` knob, given the following route:

```
apiVersion: gateway.networking.k8s.io/v1
kind: HTTPRoute
metadata:
  name: http-app-1
spec:
  parentRefs:
  - name: my-gateway
  hostnames:
  - "foo.com"
  rules:
  - matches:
    - path:
        type: PathPrefix
        value: /bar
    backendRefs:
    - name: my-service1
      port: 8080
    - name: my-service2
      port: 8080
```

The cluster alt_stat_name would look something like `default/http-app-1/default/my-service1/default/my-service2`. 

@sekar-saravanan - WDYT? 
@arkodg: I like how Istio solved this issue with a `inboundClusterStatName` setting in the top level global config https://istio.io/latest/docs/reference/config/istio.mesh.v1alpha1/

```
Name to be used while emitting statistics for inbound clusters. The same pattern is used while computing stat prefix for network filters like TCP and Redis. By default, Istio emits statistics with the pattern inbound|<port>|<port-name>|<service-FQDN>. For example inbound|7443|grpc-reviews|reviews.prod.svc.cluster.local. This can be used to override that pattern.

A Pattern can be composed of various pre-defined variables. The following variables are supported.

%SERVICE% - Will be substituted with short hostname of the service.
%SERVICE_NAME% - Will be substituted with name of the service.
%SERVICE_FQDN% - Will be substituted with FQDN of the service.
%SERVICE_PORT% - Will be substituted with port of the service.
%TARGET_PORT% - Will be substituted with the target port of the service.
%SERVICE_PORT_NAME% - Will be substituted with port name of the service.
Following are some examples of supported patterns for reviews:

%SERVICE_FQDN%_%SERVICE_PORT% will use reviews.prod.svc.cluster.local_7443 as the stats name.
%SERVICE% will use reviews.prod as the stats name.
```

Envoy Gateway can do something similar by 

1. exposing a `clusterStatsName` in EnvoyProxy under [telemetry.metrics](https://gateway.envoyproxy.io/docs/api/extension_types/#proxymetrics)
2. there can be another per route override available in BackendTrafficPolicy under `telemetry`
3. support a range of formatters from `ROUTE_KIND` , `ROUTE_NAME`, `ROUTE_RULE_NAME`, `ROUTE_RULE_NUMBER`, `BACKEND_REFS` `XDS_VHOST_DOMAIN`@guydc: > I like how Istio solved this issue with a inboundClusterStatName 

+1 to this approach@sekar-saravanan: > I like how Istio solved this issue with a inboundClusterStatName

+1 to this approach
