[#525] morph/container: Parse session token, key and signature in Get

`Get` method of `Container` contract returns binary session token, key and
signature along with container.

Provide `Signature`, `PublicKey` and `SessionToken` getters from `GetValues`
structure. Parse and set all values in `Client.Get` methods.
