NeoFS network dictates the limitation of the maximum size of the "finished"
objects. The payload size of an object is recorded in its header. When
writing finished objects, the nodes must check:
* satisfying the constraint;
* matching the value in the header to the number of payload bytes.
Provide value returned by `MaxSizeSource` component to `validatingTarget`.
Check max size value during the stream of the "finished" objects. Check
header value during the streaming and on-close. Check payload size in v2
relay scenario.

Session tokens have limited lifetime in NeoFS. Container processor should
verify lifetime of the incoming tokens.
Define `NetworkState` interface with `Epoch` method to get number of the
current epoch. Use Netmap contract client's wrapper as `NetworkState` of
Container `Processor`. Check values of token lifetime, and deny if:
* NBF value is gt the current epoch;
* IAT is gt the current epoch;
* EXP is le the current epoch.

- token owner should be the owner of the related container;
- the intent must be signed with a session key;
- the power of attorney must be signed by the owner of the container.

- session token should have container session context;

All client wrappers should use underlying static client with enabled notary

Signed-off-by: Leonard Lyubich <leonard@nspcc.ru>
Some of the client wrapper's methods should produce notary contract's
invocations. In previous implementation all wrappers provided separate
methods to do it. Since notary and non-notary invocation scenarios have very
different goals, it makes sense to separate the scenarios of using the
client wrapper at the stage of its creation.
Define `Option` constructor for container client wrapper. Add `TryNotary`
option which enables tries of the notary invocations on underlying static
client. Mark all notary-dedicated methods as deprecated.
Signed-off-by: Leonard Lyubich <leonard@nspcc.ru>
There are two scenarios of invocation of contract methods:
1. do not invoke notary contract;
2. try to invoke notary contract if it is enabled in Client.
Taking this into account, `StaticClient` can work in one of the two described
modes. Based on this, it makes sense at the stage of creating `StaticClient`
to fix the call mode, and the further abstract from it.
Define `StaticClientOption` setters of `StaticClient` optional parameters.
Add `TryNotary` constructor of option which enables notary tries. Call
`NotaryInvoke` on underlying `Client` if the option is provided, otherwise
call `Invoke`. Mark `NotaryInvoke` method of `StaticClient` as deprecated.
