To Tim,

This is the version before we talked today, I want to upload it first,
in case you want to see it.
=====================================================================
Add Information Schema
 part I, add "impala-metrics" table to Information Schema

there are questions in doubt at some place
such as
1. what is SlotDescriptor, TableDescriptor, ColomnDescriptor and where
do they come from
2. how to get NetworkAddress of all hosts
