All sessions in NeoFS has limited in epochs lifetime. There is a need
to limit the lifetime of private session tokens.
This commmit:
* extends PrivateToken interface with Expired method;
* defines EpochLifetimeStore interface with RemoveExpired method
and embeds it to PrivateTokenStore interface;
* adds epoch value parameter to private token constructor.
