Changes to the wix-data overall processing time

We had made some changes to the wix-data overall processing time calculation . Originally overall processing time was calculated on the database level, while now we moved this calculation to the API layer.

Our motivation was to make this calculation more transparent. Having overall processing time calculated on database while RPM throttling on API level was confusion. I addition, users did not have access to the database layer info (as wix-data API requests in the logs represent API layer). Thus we decided to unify it. As a result the move to the API layer, we have increased the quotas, this was needed to account for the additional time that API layer adds. We do not anticipate user impact following this change.
