Updated UPGRADING file with details on how to modify the database to accommodate the changes to policyd

NOTE: This commit will change the behaviour of message size counters used in policyd!

The following changes will need to be made to your database:

UPDATE quotas_limits, quotas_tracking
               SET quotas_limits.CounterLimit = ceil(quotas_limits.CounterLimit / 1024),
               quotas_tracking.Counter = ceil(quotas_tracking.Counter / 1024)
               WHERE quotas_tracking.QuotasLimitsID = quotas_limits.ID
               AND quotas_limits.Type = "MessageCumulativeSize";

UPDATE session_tracking        SET Size = ceil(Size / 1024);
