Relax validation for expose.paths config (#10394)
Previously we would return an error if duplicate paths were specified.
This could lead to problems in cases where a user has the same path,
say /healthz, on two different ports.

This validation was added to signal a potential misconfiguration.
Instead we will only check for duplicate listener ports, since that is
what would lead to ambiguity issues when generating xDS config.

In the future we could look into using a single listener and creating
distinct filter chains for each path/port.

Save exposed ports in agent's store and expose them via API (#10173)
* Save exposed HTTP or GRPC ports to the agent's store
* Add those the health checks API so we can retrieve them from the API
* Change redirect-traffic command to also exclude those ports from inbound traffic redirection when expose.checks is set to true.

Mark Anderson 8040f91a43 Add support for downstreams
Enhance config by adding SocketPath and LocalSocketPath config values

Supports syntax of the form:
```
services {
  name = "sock_forwarder"
  id = "sock_forwarder.1"
  socket_path = "/tmp/downstream_3.sock"
  connect {
    sidecar_service {
      proxy {
	local_service_socket_path = "/tmp/downstream.sock"
      }
    }
  }

The field was not being included in the cache info key. This would result in a DNS request for

not be the same.

Daniel Nephin d113f0e690 structs: Fix printing of IDs
These types are used as values (not pointers) in other structs. Using a pointer receiver causes
problems when the value is printed. fmt will not call the String method if it is passed a value
and the String method has a pointer receiver. By using a value receiver the correct string is printed.

Also remove some unused methods.

server: create new memdb table for storing system metadata (#8703)
This adds a new very tiny memdb table and corresponding raft operation
for updating a very small effective map[string]string collection of
"system metadata". This can persistently record a fact about the Consul
state machine itself.

The first use of this feature will come in a later PR.

add primary keys to list keyring (#8522)
During gossip encryption key rotation it would be nice to be able to see if all nodes are using the same key. This PR adds another field to the json response from `GET v1/operator/keyring` which lists the primary keys in use per dc. That way an operator can tell when a key was successfully setup as primary key.

Based on https://github.com/hashicorp/serf/pull/611 to add primary key to list keyring output:

```json
[
  {
    "WAN": true,
    "Datacenter": "dc2",
    "Segment": "",
    "Keys": {
      "0OuM4oC3Os18OblWiBbZUaHA7Hk+tNs/6nhNYtaNduM=": 6,
      "SINm887hKTzmMWeBNKTJReaTLX3mBEJKriDyt88Ad+g=": 6
    },
    "PrimaryKeys": {
      "SINm887hKTzmMWeBNKTJReaTLX3mBEJKriDyt88Ad+g=": 6
    },
    "NumNodes": 6
  },
  {
    "WAN": false,
    "Datacenter": "dc2",
    "Segment": "",
    "Keys": {
      "0OuM4oC3Os18OblWiBbZUaHA7Hk+tNs/6nhNYtaNduM=": 8,
      "SINm887hKTzmMWeBNKTJReaTLX3mBEJKriDyt88Ad+g=": 8
    },
    "PrimaryKeys": {
      "SINm887hKTzmMWeBNKTJReaTLX3mBEJKriDyt88Ad+g=": 8
    },
    "NumNodes": 8
  },
  {
    "WAN": false,
    "Datacenter": "dc1",
    "Segment": "",
    "Keys": {
      "0OuM4oC3Os18OblWiBbZUaHA7Hk+tNs/6nhNYtaNduM=": 3,
      "SINm887hKTzmMWeBNKTJReaTLX3mBEJKriDyt88Ad+g=": 8
    },
    "PrimaryKeys": {
      "SINm887hKTzmMWeBNKTJReaTLX3mBEJKriDyt88Ad+g=": 8
    },
    "NumNodes": 8
  }
]
```

I intentionally did not change the CLI output because I didn't find a good way of displaying this information. There are a couple of options that we could implement later:
* add a flag to show the primary keys
* add a flag to show json output

Fixes #3393.
