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.
