To fine-tune read/write/delete load we need to have separate sleep
intervales for readers/writers/deleters.

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.

1. Implement reset method that allows to start iteration from beginning of
the registry. This allows to revisit objects in scenarios like object
deletion.
2. Add filter structure that allows to select objects based on age.

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.

It improves payload generation in our scenarios. Current implementation
of scenarios generates single random payload at the start and then sends this
same payload on every request. More realistic test is to generate unique payload
for each request. However, this is an expensive operation that can easily cause
a bottleneck on K6 side when we run multiple writing VUs. So instead we generate
a random buffer with some extra bytes and then take slices of this buffer thus
producing a random payload for each request.
