Lint for variable extraction if the function argument is too long

Less readable:
```
self.reader(table_query)
.options(**self._get_jdbc_reader_options(jdbc_reader_options) | self._get_timestamp_options())
```

More readable:
```
options = self._get_jdbc_reader_options(jdbc_reader_options) | self._get_timestamp_options()
self.reader(table_query).options(**options)
```
