It is the heaviest function executing on setup stage.
The culprit is the linear dependency between its execution
time and the amount of objects in registry. The solution is to store
object by status. While the optimization doesn't work for objects with
no status, it is currently provided by all scenarios.

1. Get rid of JSON in the database.
2. Store `CreatedAt` as int64. It decreases JSON marshaling time by
about ~25% with no changes for native scheme.

Includes:
1. Logic simplification: no need to call `ObjSelector.Reset` from JS code,
everything could be done inside the Go code. Remove unused mutexes.
2. Do not handle object twice ever: Once handled, any error is expected to be
logged on the JS side and never be handled again. It solves "already removed"
error.
3. Object caching: no need to call bolt's `View` on every object removal: it
blocks other calls and slows down the execution. Read 100 objects (or less if
not available yet), cache them and send to buffered channel.

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.
