IMPALA-8547: get_json_object fails to get value for numeric key
Allows numeric keys for JSON objects in get_json_object. This patch
makes Impala consistent with Hive and Postgres behavior for
get_json_object.
Queries such as "select get_json_object('{"1": 5}', '$.1');"
would fail before this patch. Now the query will return '5'.
Testing:
* Added tests to expr-test

> {code:java}
> "Expected key at position 2"

> I guess it's caused by using function FindEndOfIdentifier that expects first
> symbol of key to be a letter.
> Hive version of get_json_object works fine in this case.
