Merged PR 3279: Remove unused code: additive contribution to churn and its metrics

Browse source 
# Description

Simplifies the code for the models:
* int_monthly_12m_window_contribution_by_deal
* int_monthly_churn_metrics

By just removing the additive contribution approach. This also reduces the schema file information of these 2 models. I also adapted the description to clarify the state of the models.

No rush to merge this.

# 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.
- [X] I have checked for DRY opportunities with other models and docs.
- [X] I've picked the right materialization for the affected models.

# Other

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

There's 2 different contribution methods, the additive and
the average approach. The additive approach will "penalise"
accounts that have been active for less than 12 months on the
contribution amount, while the average approach "boosts" the
contribution of those accounts that have been active for less
than 12 months.
Mathematically speaking, it is encouraged to use the additive
approach ;-)
Find below the details of the computation:
- Additive approach:
Over a period of 12 months, sum the value of a given a metric
for each deal. Sum all the deals to get a global. Divide the
deal value vs. the global one.
- Average approach:
The contribution is based on an Average approach:
Over a period of 12 months, sum the value of a given a metric
for each deal, and divide it by the amount of months we're considering
for that deal. Sum all the average amounts per deals to get a global.
Divide the avg per deal value vs. the sum of avgs global one.
The average approach "boosts" the contribution of those accounts
that have been active for less than 12 months.

This model retrieves the 12 month contribution to global metrics
