[NET-4897] net/http host header is now verified and request.host that contains socked now error (#18129)
### Description

This is related to https://github.com/hashicorp/consul/pull/18124 where
we pinned the go versions in CI to 1.20.5 and 1.19.10.

go 1.20.6 and 1.19.11 now validate request host headers for validity,
including the hostname cannot be prefixed with slashes.

For local communications (npipe://, unix://), the hostname is not used,
but we need valid and meaningful hostname. Prior versions go Go would
clean the host header, and strip slashes in the process, but go1.20.6
and go1.19.11 no longer do, and reject the host header. Around the
community we are seeing that others are intercepting the req.host and if
it starts with a slash or ends with .sock, they changing the host to
localhost or another dummy value.

Accept ap, datacenter, and namespace query params (#17525)
This commit only contains the OSS PR (datacenter query param support).
A separate enterprise PR adds support for ap and namespace query params.

Resources in Consul can exists within scopes such as datacenters, cluster
peers, admin partitions, and namespaces. You can refer to those resources from
interfaces such as the CLI, HTTP API, DNS, and configuration files.

Some scope levels have consistent naming: cluster peers are always referred to
as "peer".

Other scope levels use a short-hand in DNS lookups...
- "ns" for namespace
- "ap" for admin partition
- "dc" for datacenter

...But use long-hand in CLI commands:
- "namespace" for namespace
- "partition" for admin partition
- and "datacenter"

However, HTTP API query parameters do not follow a consistent pattern,
supporting short-hand for some scopes but long-hand for others:
- "ns" for namespace
- "partition" for admin partition
- and "dc" for datacenter.

This inconsistency is confusing, especially for users who have been exposed to
providing scope names through another interface such as CLI or DNS queries.

This commit improves UX by consistently supporting both short-hand and
long-hand forms of the namespace, partition, and datacenter scopes in HTTP API
query parameters.

Add support for merge-central-config query param (#13001)
Adds a new query param merge-central-config for use with the below endpoints:

/catalog/service/:service
/catalog/connect/:service
/health/service/:service
/health/connect/:service

If set on the request, the response will include a fully resolved service definition which is merged with the proxy-defaults/global and service-defaults/:service config entries (on-demand style). This is useful to view the full service definition for a mesh service (connect-proxy kind or gateway kind) which might not be merged before being written into the catalog (example: in case of services in the agentless model).

agent: return the default ACL policy to callers as a header (#9101)
Header is: X-Consul-Default-ACL-Policy=<allow|deny>

This is of particular utility when fetching matching intentions, as the
fallthrough for a request that doesn't match any intentions is to
enforce using the default acl policy.

add flag to allow /operator/keyring requests to only hit local servers (#6279)
Add parameter local-only to operator keyring list requests to force queries to only hit local servers (no WAN traffic).

HTTP API: GET /operator/keyring?local-only=true
CLI: consul keyring -list --local-only

Sending the local-only flag with any non-GET/list request will result in an error.

R.B. Boyer cc1aa3f973 acl: adding Roles to Tokens (#5514)
Roles are named and can express the same bundle of permissions that can
currently be assigned to a Token (lists of Policies and Service
Identities). The difference with a Role is that it not itself a bearer
token, but just another entity that can be tied to a Token.

This lets an operator potentially curate a set of smaller reusable
Policies and compose them together into reusable Roles, rather than
always exploding that same list of Policies on any Token that needs
similar permissions.

This also refactors the acl replication code to be semi-generic to avoid
3x copypasta.

Implement data filtering of some endpoints (#5579)
Fixes: #4222 

# Data Filtering

This PR will implement filtering for the following endpoints:

## Supported HTTP Endpoints

- `/agent/checks`
- `/agent/services`
- `/catalog/nodes`
- `/catalog/service/:service`
- `/catalog/connect/:service`
- `/catalog/node/:node`
- `/health/node/:node`
- `/health/checks/:service`
- `/health/service/:service`
- `/health/connect/:service`
- `/health/state/:state`
- `/internal/ui/nodes`
- `/internal/ui/services`

More can be added going forward and any endpoint which is used to list some data is a good candidate.

## Usage

When using the HTTP API a `filter` query parameter can be used to pass a filter expression to Consul. Filter Expressions take the general form of:

```
<selector> == <value>
<selector> != <value>
<value> in <selector>
<value> not in <selector>
<selector> contains <value>
<selector> not contains <value>
<selector> is empty
<selector> is not empty
not <other expression>
<expression 1> and <expression 2>
<expression 1> or <expression 2>
```

Normal boolean logic and precedence is supported. All of the actual filtering and evaluation logic is coming from the [go-bexpr](https://github.com/hashicorp/go-bexpr) library

## Other changes

Adding the `Internal.ServiceDump` RPC endpoint. This will allow the UI to filter services better.

Grégoire Seux 4f62a3b528 Implement /v1/agent/health/service/<service name> endpoint (#3551)
This endpoint aggregates all checks related to <service id> on the agent
and return an appropriate http code + the string describing the worst
check.

This allows to cleanly expose service status to other component, hiding
complexity of multiple checks.
This is especially useful to use consul to feed a load balancer which
would delegate health checking to consul agent.

Exposing this endpoint on the agent is necessary to avoid a hit on
consul servers and avoid decreasing resiliency (this endpoint will work
even if there is no consul leader in the cluster).
