Merged PR 2221: Computes (paid) guest revenue metric - fixed

IMPORTANT: this PR was merged and reverted. The division by 0 error has been fixed in the last commit

Adds the following metrics:
- Guest Revenue

by both visions (global and by deal id)
It creates 2 new models:
- int_mtd_guest_revenue_metrics
- int_monthly_guest_revenue_history_by_deal

the approaches are similar in the sense that we retrieve the information from the int_core__verification_payments and a filter by a PAID status. I checked and the aggregated volumes of the figures correspond to the decimal as what is reported to the guest_payments dashboard (aggregating the information from the currency tab)

Same as last PR, this one does not exposes the data since a refactor of how the code is structured will follow shortly.
