Merged PR 3651: Adding billing_country as dimension and new aggregated model

# Description

Added billing_country as dimension to use in the Guest KPIs Report.
Also created a new model that pivots the metrics to leave them as a column and aggregates the values set for different timeframes (YTD, MTD, WTD). For the moment it only aggregates the values for the existing metrics on the existing models, it doesn't compute metrics like rates or averages (avg_csat_score, conversion_rate, etc..). I am not sure if it would be better to compute here in the model or just doing it in PBI, both are viable options not sure if the model is going to end up being too monstrous or it doesn't matter.
@<Oriol Roqué Paniagua> what do you think??
