    I think we should stick to json standard and leave them switched off by 
default. If user get an exception we may show the option name which he want to 
switch on.

> Add session options to allow drill working with non standard json strings 
> number literals like: NaN, Infinity, -Infinity. By default these options will 
> be switched off, the user will be able to toggle them during working session.
> *For documentation*
> 1. Added two session options {{store.json.reader.non_numeric_numbers}} and 
> {{store.json.reader.non_numeric_numbers}} that allow to read/write NaN and 
> Infinity as numbers. By default these options are set to false.
> 2. Extended signature of {{convert_toJSON}} and {{convert_fromJSON}} 
> functions by adding second optional parameter that enables read/write NaN and 
> Infinity.
> For example:
> {noformat}
> select convert_fromJSON('{"key": NaN}') from (values(1)); will result with 
> JsonParseException, but
> select convert_fromJSON('{"key": NaN}', true) from (values(1)); will parse 
> NaN as a number.
> {noformat}
