HostAndPortDeserializer rely on older version property name

[Nireus]

HostAndPortDeserializer should use field name host instead of hostText

jackson-datatypes-collections:guava

@Override
    public HostAndPort deserialize(JsonParser p, DeserializationContext ctxt)
        throws IOException
    {
        // Need to override this method, which otherwise would work just fine,
        // since we have legacy JSON Object format to support too:
        if (p.currentToken() == JsonToken.START_OBJECT) { // old style
            JsonNode root = p.readValueAsTree();
            String host = root.path("hostText").asText();
            JsonNode n = root.get("port");
            if (n == null) {
                return HostAndPort.fromString(host);
            }
            return HostAndPort.fromParts(host, n.asInt());
        }
        return super.deserialize(p, ctxt);
    }

First question: which library is this about? Guava? If so, could you please add Label to indicate that?

Second: Assuming this is Guava, we may have a problem: Jackson does not require Guava 20; for 2.9 and 2.10 minimum version is 18. Ideally it would work with multiple versions.
But as long as we can accept either host or hostText that should be fine: code should be able to check newer field (I think) first, and only if not found, older.
