1. Added simple lock mechanism to reset obj selector. This prevents
most of concurrency issues when multiple VUs try to reset selector.
2. Added logic to delete objects to grpc and s3 scenarios.
3. Added registry support to http scenario.
4. Deletion logic was not implemented for http scenario, because
http gateway does not provide web-method to delete objects.

Registry module stores information about uploaded objects in bolt database and
allows to verify their validity after a load test.
Also, implemented logic to verify objects uploaded via gRPC and S3 protocols.
