In previous implementation `verifySignature` method of container
processor worked incorrectly for operations without a key and with
session: processor tried to verify signature with one of the bound owner
keys instead of session one.
Use `VerifySessionDataSignature` method to check the signature if
session is used. Refactor `verifySignature` a bit with session check
highlighting for readability.

Core changes:
* avoid package-colliding variable naming
* avoid using pointers to IDs where unnecessary
* avoid using `idSDK` import alias pattern
* use `EncodeToString` for protocol string calculation and `String` for
printing

In previous implementation IR incorrectly verified `SetEACL` event of
`Container` contract. The incorrect behavior could be reproduced in two
ways:
1. Create container using session, and perform `SetEACL` operation
with a key that is different from the session one.
2. Create container using session, and perform `SetEACL` w/o a
session, but sign it using session key from the `Put` operation.
The problem was in the `checkSetEACL` validation method of IR container
processor. It always used session token used for container creation
during session ownership check.

Add name and zone arguments to `Put` method of wrapper over the Container
contract client. Pass result of `container.GetNativeNameWithZone` function
to the method in `Put` helper function. Due to this, the storage node will
call the method depending on the presence of the container name in the
attributes.
Make IR to listen `putNamed` notification event. The event is processed like
`put` event, but with sanity check of the container attributes.

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 of the container session should be written out with container context.
The context should have the verb corresponding to the operation. If an
operation is performed on a fixed container, the session should be
propagated to it or to all user containers

events.

Session token can be presented `Put`, `Delete` and `SetEACL` notification
events. IR should consider this case as issuing a power of attorney to a
third party. Thus, checking the eligibility for an operation should be
complicated:
- 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.
Omitted checks (TBD):
- session token should have container session context;
- the verb of the context should correspond to the operation.
