Description

The current implementation of CounterColumn keeps both the partitioned
counter and the total value of the counter (that is, the sum of the parts of
the partitioned counter).
This waste space and this requires the code to keep both representation in
sync. This ticket propose to remove the total value from the representation
and to only calculate it when returning the value to the client.

NOTE: this breaks the on-disk file format (for counters)
