[FR]: Add resource-specific defaults/merges/overrides to modules/project-factory

[juliocc]

The feature request

The PF currently uses three variables—data_defaults, data_merges, and data_overrides—to modify project attributes. However, the PF also creates folders and billing budgets, which these variables do not affect.

Allow the project factory to modify the attributes of the other resources it creates.

Proposed solution

Two possible solutions:

1. Rename the existing variables to be explicit about their purpose e.g. project_defaults, project_merges, project_overrides.
2. Add top-level keys to the existing data_* variables representing the resource they alter. Something like this

variable "data_merges" {
  type = object({
    project = optional(object({...}))
    folders = optional(object({...}))
  })
}

Additional context

It's now 3:3 (defaults, merges and overrides vs project, folders and budgets), but I vote for 2, as this will be anyway backward incompatible change. And it might grow to 3:n in future.
