feat(sweepers): allow sweepers to be scoped to the default project id

[DorianMaliszewski]

The feature

• Allow user to scope the e2e sweepers to the default project id only and not every project in the organization

Implementation

• Use a flag projectScoped that change the function behavior when set to true.
• Functions will only target the SCW_DEFAULT_PROJECT_ID passed instead of all projects in the organization
• For some sweepers we need to make a first call that list the resources to target in the project (like crons in functions)
