645a8653c895e4fc7717e9e5ac045612b5deaa60 rpc: remove deprecated getaddressinfo `label` field (Jon Atack)
Pull request description:
These were deprecated in #17578 and #17585, with expected 0.21 removal notified in the 0.20 release notes.
```
- The `getaddressinfo` RPC has had its `label` field deprecated
(re-enable for this release using the configuration parameter
`-deprecatedrpc=label`). The `labels` field is altered from returning
JSON objects to returning a JSON array of label names (re-enable
previous behavior for this release using the configuration parameter
`-deprecatedrpc=labelspurpose`). Backwards compatibility using the
deprecated configuration parameters is expected to be dropped in the
0.21 release. (#17585, #17578)
