[#202] session: Support sessions issued for an object group

Browse source 
Sometimes it is useful to open single session which covers several
objects in the container. In previous implementation it could be done:
 * by opening container-global session
 * by opening N per-object sessions

Both approaches are not optimal for the mentioned need.

Define `ObjectSessionContext.Target` which is backward compatible with
`refs.Address` in binary format. Replace `address` field of
`refs.Address` type in `ObjectSessionContext` message with `target`
field of `ObjectSessionContext.Target` type. This change saves backward
compatibility in binary format, but break the JSON one. Such a breakage
is considered admissible for now since NeoFS API protocol hasn't
declared JSON compatibility yet.
