feat(modular): add TF snippets for enable GCP APIs

xref: https://sysdig.atlassian.net/browse/SSPROD-46145

This is a WIP for providing TF snippets to enable GCP APIs to customer so they don't have to do it manually.

All is working and the APIs are enabled properly for the GCP project and organization. The only thing that needs to be done is the scrapping of the folders within a GCP organization since the google_projects resource only provides the root projects within the organization and not the ones within folders, basically for a scenario like:

• MyOrg
  • MyProject1
  • MyProject2
  • MyFolder1
    • MyProject3

The google_projects resource is only retrieving the projects: MyProject1 and MyProject2. In order to change this I'll need to use another resource that grabs the folders and create a recursive functionality to scrape all the Org - working on this already.

Update:
This was done via a null_resource resource in TF, basically this resource makes some API calls using gcloud and the context of the user machine to create a recursive function that scrapes the whole organization, after that a json file is saved to the local directory and then this is used to create the API enablement resources.

TF does not let a plan or apply step without knowing the data that it's going to be scraped so a target apply needs to be done prior since the null_resource is only executed during an apply, the command will be:

terraform init && terraform apply -target=null_resource.get_projects_from_folders --auto-approve && terraform apply --auto-approve

With this command, we make sure that the projects from folder are picked before starting the API enablement. It's also an easier way to avoid more work for the user.

LGTM, let's add the folders list + projects underneath each to the final projects list and we can merge this 👍

@jose-pablo-camacho Talked to @claffin for feedback, let's stick to TF inline calling the bash script to recursively call it for now, as you have it 👍 We will then get some feedback from PS (Support) team next to see if they find it useful.

@haresh-suresh Sounds good! So let me know if it looks good, I can merge this
