Redash queries crash if numerical column contain NaN

[noxdafox]

Issue Summary

The following commit 4d51039, introduced a regression. As simplejson was replaced with json strict JSON validation is now enforced.

The belief is that JSON validation was enforced to prevent the json module to return NaN values which break the frontend:
https://github.com/getredash/redash/blob/master/redash/utils/__init__.py#L129

    # Using allow_nan = True will make Python render nan as NaN, leading to parse error in front-end

Yet, the change and the comments suggest that this was not the expected behaviour:
https://github.com/getredash/redash/blob/master/redash/utils/__init__.py#L128

    # Float value nan or inf in Python should be render to None or null in json.

Previous to that commit, NaN values were allowed and automatically converted to None by simplejson. json does not support this functionality and now the behaviour is to raise ValueError effectively crashing the query every time a NaN value is encountered.

ValueError: Out of range float values are not JSON compliant

This is breaking several of our queries as null values are acceptable in many DB implementations in place of floats/doubles/reals.

To revert back to the previous behaviour, either simplejson is reinstated as JSON serialization library, or a custom JSONEncoder class is provided (and maintained) instead:

Technical details:

• Redash Version: preview
• Browser/OS: any
• How did you install Redash: Docker

This problem is originated by the PR #6685 . I think it's made huge interoperability problem.

I suggest to use orjson. It allows nan, too. In general, it's faster than json and simplejson.
