STATISTICS: add total counts for number of delegations and number of revokes

Browse Source 
Everytime we give a delegation to another node we count this as one delegation.
If the same record is delegated to several nodes we count one for each node.

Everytime a record has all its delegations revoked we count this as one revoke.
