All import tasks are assigned to the same worker

Task `import_collection` now uses resource reservation. It reserves two resources: an artifact and a related repository.
When scheduling a task, the resource manager assigns task that has a resource reservations on a worker that runs a task with any of requested reservations. This causes the following side effect:
Because repository is a global object, all tasks related to that repository are always run sequentially due to being assigned on the same worker.
