Add `data` metrics to measure payload rate.
Rename `total` metrics to `success`, because these metrics count
success operations count but not total operations count.

Return an interface which can be converted to `io.Reader` as well as
report payload size and hash.

Previous iteration was bad, because `Logger` instance was shared and
endpoints in different VUs were overriding each other.
New interface is much better, it supports logger extension in any
context with arbitrary fields.
```
const l = logging.new().withFields({endpoint: "my endpoint"});
...
l.withField("cid", container).info("not found");
```

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.

At the moment we don't need logic that swings back to beginning of registry when
all objects have been processed. So, for now we can stop iterating and return an
error when selector reaches the end of registry.

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.
