Merged PR 3461: Creates models for listing metrics

# Description

Adds listing metrics model. It's a bit similar as the Deal metrics, but here we can aggregate by deal :)

I'm aware that int_kpis__metric_daily_listings takes quite a bit (3 min). To be optimised later on.

# Checklist

- [X] The edited models and dependants run properly with production data.
- [X] The edited models are sufficiently documented.
- [X] The edited models contain PK tests, and I've ran and passed them.
- [ ] I have checked for DRY opportunities with other models and docs.
- [ ] I've picked the right materialization for the affected models.

# Other

- [ ] Check if a full-refresh is required after this PR is merged.
