Fixes Hbase metadata query return wrong result

Based on current implement of Hbase metadata query  in Ceilometer,
it's trying to compare the metadata value with the metadata stored
in table "resource" instead of table "meter", when user query a
specific meter name. As a result, the query result will be wrong.
