Make `Get` method of the wrapper over Container contract's client to
accept binary container ID. Create `Get` function similar to the previous
`Get` variation. Use this function in Container service server in the place
where `Get` method was used.
Additionally implement `AsContainerSource` function which allows
to simply compose container Source interface from the wrapper.

Make `Delete` method of the wrapper over Container contract's client to accept
two binary parameters: container ID and signature. Create `Delete` function
similar to the previous `Delete` variation, but accepting `Signature`
structure instead of binary signature. Use this function in Container
service server in the place where `Delete` method was used.

Make `Put` method of the wrapper over Container contract's client to accept
three binary parameters: container, key and signature. Create `Put` function
similar to the previous `Put` variation, but accepting `Signature`
structure instead of binary key and signature. Use this function in
Container service server in the place where `Put` method was used.

In recent changes argument list of set eACL call of Container contract
client was extended with binary public key. In the future there will be a
need to pass the table in binary format.
Replace `PutEACL` method with `PutEACLBinary` one which accepts three binary
parameters: eACL table, key and signature. Create `PutEACL` function similar
to the removed method, but accepting `Signature` structure instead of just
a signature. Use this function in Container service server in the place
where `PutEACL` was used.

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.

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.

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.

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.

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.
