client: Some ContainerService.GetResponse fields are ignored

NeoFS API client ignores
https://github.com/nspcc-dev/neofs-api/blob/62e4ae0f8d62987cb54ab729b16b4f9ed4c0ad4c/container/service.proto#L215-L219

this is either:

1. bug, and client must start to check these fields
2. redundant information that should be eliminated from the protocol

i'd stand for 2 since fields are not returned, currently nobody is interested in verification info and is satisfied with the container presence

same for GetExtendedACL

If it ended up in the contract, it can be considered valid, no need to check it additionally. But it's not trivial to remove now at the same time.
