Piotr Grabowski efe7456f0a type_json: support integers in scientific format ...

Add support for specifing integers in scientific format (for example
1.234e8) in INSERT JSON statement:

INSERT INTO table JSON '{"int_column": 1e7}';

Inserting a floating-point number ending with .0 is allowed, as
the fractional part is zero. Non-zero fractional part (for example
12.34) is disallowed. A new test is added to test all those behaviors.

Before the JSON parsing library was switched to RapidJSON from JsonCpp,
this statement used to work correctly, because JsonCpp transparently
casts double to integer value.

This behavior differs from Cassandra, which disallows those types of
numbers (1e7, 123.0 and 12.34).

Fix typo in if condition: "if (value.GetUint64())" to
"if (value.IsUint64())".

Fixes #10100
