Make the default hitsAddend configurable

[gcalmettes]

The current minimum hitsAddend value is set to 1 (enforced via a Max function). This prevents uses cases where the request itself would not carry any "weight" (e.g.: request to check a quota).

Could we make the minimum hitsAddend value configurable so 0 could also be a possible hitsAddend value for a request ?
