> Parquet files contain metadata about rowcount & file size. We should have new commands to get rows count & size.
> These command can be added in parquet-tools:
> 1. rowcount : This should add number of rows in all footers to give total rows in data. 
> 2. size : This should give compresses size in bytes and human readable format too.
> These command helps us to avoid parsing job logs or loading data once again to find number of rows in data. This comes very handy in complex processes, stats generation, QA etc..
