> We should improve the extraction of {{TableSchema}} from
> {{DataStream/DataSet}}. Currently it is split into a few stages:
> # Extract types ignoring time attributes via {{FieldInfoUtils#getFieldInfo}}
> # Extract the rowtime and proctime positions via
> {{StreamTableEnvImpl#validateAndExtractTimeAttributes}}
> # Adjust the indices from #1 using information from #2
> All that could happen in a single pass. This will also deal with the
> porting/removing of a few methods from {{StreamTableEnvImpl}}.
