[#1569] cli: Make --range flag required in object hash

Browse source 
Previously, `object head` was used if no range was provided.
This is wrong on multiple levels:
1. We print an error if the checksum is missing in header,
   even though taking hash is possible.
2. We silently ignore --salt parameter.
3. `--range` is required for Object.RANGEHASH RPC, custom logic for one
   specific usecase has no value.

So we make it required and make CLI command follow more closely
the FrostFS API.
