There's sometimes a need to add custom attribute to Scan object so that it can be accessed on server side.
Example of the case where it is needed discussed here: http://search-hadoop.com/m/v3Jtb2GkiO. There might be other cases where it is useful, which are mostly about logging/gathering stats on server side.
Alternative to allowing adding any custom attributes to scan could be adding some fixed field, like "type" to the class.
