audit: refactor into functions
audit: refactor into functions

mechanical refactor into functions:

- remove_all_gcp_project_audit_files
- audit_gcp_organization
- audit_all_gcp_projects_with_parent_id
- audit_gcp_project
- audit_gcp_project_service
- main

ensure each function removes whichever folder it is about to populate,
instead of deleting everything up front (to support targeted audits),
except for audit_all_gcp_projects_with_parent_id, since it's populating
a flat/non-hiearchical folder that may contain projects with other
parent id's

touch up logging for consistency
