21133aee2f [] container/load: Implement route builder based on placement
Implement route Builder interface on wrapper over the container placement
builder, Component implies exactly one transfer to each of the most weight
nodes of the container (according to some weighing algorithm).
Implementation is planned for use when transferring local estimates of
storage nodes.

d48fb81193 [] container/load: Implement route controller
Implement a component for transmitting the value of the used container space
along a route defined in the system. Implement WriterProvider interface on
it. By implementation, it is the link between the route planner and the
point-to-point transmitter, and abstracts from the implementation of both of
them. In the future, this implementation will be used as a transmitter of
local estimates of storage nodes among themselves.

4415f8dc5b [] container/load: Implement simple Iterator and Writer providers
Implement functions to wrap Writer or Iterator. The resulting wrapper
provides WriterProvider or IteratorProvider interface respectively.
Such a wrapper can be used as a single storage instance provider
regardless of context.

2622e11ae3 [] container/load: Implement local storage of used space announcements
Implement a component that stores the values of the used space of
containers. The storage allows you to write several values for a fixed
container and epoch number, and read the averaged estimates of all
accumulated values. All values are stored in memory. This component is
planned to be used as an accumulator of opinions from various network
participants about the fullness of the container.

cc88320d6b [] container/load: Implement a metrics exchange controller
Implement a component that connects the value stores of the used space of
containers. Implement the Start/Stop operations on it, which will later
become the application handlers of the corresponding events from the
sidechain. The main task of the controller is to temporarily synchronize the
stages of calculating the global estimate of the used space in the
container. The details of the score calculation (the way of collecting /
transmitting local scores, the final score formula and writing to the
contract) are encapsulated in the dependency components, the controller is
abstracted from them.
