> 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}
