[DISCUSS][2.0] FLIP-351: REST API normalizes +/-Inf / NaN to 0

[Chesnay Schepler]

There are a number of cases where the REST API can return infinity or 
NaN for certain double fields.

This is problematic because the JSON spec does not allow such values, 
and tooling working against that spec may run into issues when 
encountering such a value.

Specifically we've seen this become an issue in clients generated from 
the OpenAPI spec.
