Merged PR 2105: Adding listing lifecycle metrics into business KPIs

This PR will compute the listing metrics in an aggregated manner to be displayed in the Main KPIs dashboard, specifically:
- New Listings
- First Time Booked Listings
- Churning Listings
- It also adapts the computation for the already existing metrics of Listings Booked in X months

At code level, it contains the following:
- Adds `int_core__mtd_accommodation_metrics`, which computes the aggregation of the lifecycle of listings at date level (unique), being date the corresponding date from `int_dates_mtd`
- Changes `int_core__mtd_aggregated_metrics` to take the accommodation metrics from the new model. Those 3 already existing (Listings booked in X month) now read from the new model as well.
- Changes `int_core__mtd_booking_metrics` to remove unused computation, making it lighter. Specifically, it removes 1) listing related metrics, since now we have a dedicated model and 2) number of guests booked, since it's not used at all.

The resulting values in local are consistent with what is already reported in the staging report.
