2f38fef31a [#589] ir/container: Verify session token lifetime
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.

23c5277014 [#525] ir/container: Check session verb and container ID
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

Implement all described checks in validation of `Put` / `Delete` / `SetEACL`
events.

ead4513feb [#525] ir/container: Verify operations with session token
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.

additional verification of key ownership is required.

5287c194e5 [#505] ir/container: Replace key ownership check into a separate method
Method of key ownership verification is going to be reused by the handlers
of the other events.
