Amnon Heiman abbd78367c Add configuration to disable per keyspace and column family metrics ...

The number of keysapce and column family metrics reported is
proportional to the number of shards times the number of keysapce/column
families.

This can cause a performance issue both on the reporting system and on
the collecting system.

This patch adds a configuration flag (set to false by default) to enable
or disable those metrics.

Fixes #2701
