There is a need to support multiple server endpoints for reputation and
container transmission.

iterator.

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.
