I've updated the PR to also print out the fields of GenericTypes.

> Priority: Minor

> Users affected by poor performance might want to understand how Flink is
> serializing their data.
> Therefore, it would be cool to have a tool utility which logs the serializers
> like this:
> {{SerializerUtils.getSerializers(TypeInformation<POJO> t);}}
> to get
> {code}
> PojoSerializer
> TupleSerializer
> IntSer
> DateSer
> GenericTypeSer(java.sql.Date)
> PojoSerializer
> GenericTypeSer(HashMap)
> {code}
