[#1865] cli/object: Do not open remote sessions in reading ops

It does not make sense to open remote sessions with the storage node in
`get`, `head`, `search`, `range` and `hash` sub-commands of `neofs-cli
object` command.

Do not use NeoFS API `SessionService` in mentioned commands. Decode
object session from JSON file specified `--session` flag. Perform some
sanity checks instantly on CLI side.
