Merged PR 3124: 1/3 - Revenue renaming Main KPIs - MTD scope

# Description

Adapts revenue figures in Main KPIs - MTD scope or global view. This includes MTD, Monthly Overview, Global Evolution over Time, Detail by Category. In essence, everything that is not by deal.

The changes are mainly 2:
* Remove the line that deducts the `Waiver Amount Paid Back to Hosts` in all metrics except the `Waiver Net Fees`. This effectively means that the previous `Guest Revenue` = `Guest Payments`, thus I dropped all 3 `Guest Payments` metrics.
* Do a renaming at metric display level, but not in the code. This means that I remove the computation of `guest_revenue_in_gbp` for instance and keep `guest_payments_in_gbp`, and apply the renaming later on, since the modelisation already accounts for defining metric names differently from those of the fields. For the rest of metrics, I revised all metrics name and did changes based on the [whiteboard](https://whiteboard.office.com/me/whiteboards/p/c3BvOmh0dHBzOi8vZ3VhcmRob2ctbXkuc2hhcmVwb2ludC5jb20vcGVyc29uYWwvcGFibG9fbWFydGluX3N1cGVyaG9nX2NvbQ%3d%3d/b!T2D3opQuBECSDnhuFZrUacFu3TxvSvdIsnI4Dxsh2IuaB1AigbciRqkqte61I4wz/01H5SI4J4L7HTPJGUT7JGYKTOSQYYWACXU). I also changed the dedicated data tests in Main KPIs to ensure it's working. I also changed the exclusion logic in reporting based on the name of the metric to not display metrics that depend on the invoicing cycle unless it's 2 months ago or before.

To keep in mind:
* Merging this will automatically display the new figures/naming in production. Might be wise to communicate to stakeholders since some key metrics (namely, Guest Revenue / Total Revenue) will change the meaning.
* We also need to do these changes in the metrics by deal part of the computation. I'd do first the removal of these fields in the PBI report (and take the opportunity to change the Data Catalogue) and then do the PR in DWH to change the logic. Before that though let's check that the names included in this PR are the correct ones :)
