Merge #21594: rpc: add network field to getnodeaddresses

1b9189866a rpc: simplify/constify getnodeaddresses code (Jon Atack)
3bb6e7b655 rpc: add network field to rpc getnodeaddresses (Jon Atack)

Pull request description:

  This patch adds a network field to RPC `getnodeaddresses`, which is useful on its own, particularly with the addition of new networks like I2P and others in the future, and which I also found helpful for adding a new CLI command as a follow-up to this pull that calls `getnodeaddresses` and needs to know the network of each address.

  While here, also improve the `getnodeaddresses` code and help.

  ```
  $ bitcoin-cli -signet getnodeaddresses 3
  [
    {
      "time": 1611564659,
      "services": 1033,
      "address": "2600:1702:3c30:734f:8f2e:744b:2a51:dfa5",
      "port": 38333,
      "network": "ipv6"
    },
    {
      "time": 1617531931,
      "services": 1033,
      "address": "153.126.143.201",
      "port": 38333,
      "network": "ipv4"
    },
    {
      "time": 1617473058,
      "services": 1033,
      "address": "nsgyo7begau4yecc46ljfecaykyzszcseapxmtu6adrfagfrrzrlngyd.onion",
      "port": 38333,
      "network": "onion"
    }
  ]

  $ bitcoin-cli help getnodeaddresses
  getnodeaddresses ( count )

  Return known addresses, which can potentially be used to find new nodes in the network.

  Arguments:
  1. count    (numeric, optional, default=1) The maximum number of addresses to return. Specify 0 to return all known addresses.

  Result:
  [                         (json array)
    {                       (json object)
      "time" : xxx,         (numeric) The UNIX epoch time when the node was last seen
      "services" : n,       (numeric) The services offered by the node
      "address" : "str",    (string) The address of the node
      "port" : n,           (numeric) The port number of the node
      "network" : "str"     (string) The network (ipv4, ipv6, onion, i2p) the node connected through
    },
    ...
  ]
  ```
  Future idea: allow passing `getnodeaddresses` a network (or networks) as an argument to return only addresses in that network.
