Problem

There are cases where we need to find nodes storing a particular object. It seems frostfs-cli would be a right place to implement this functionality.

Proposed solution

Add frostfs-cli action to show a list of nodes that may have an object passed as argument by address. There also should be an option that makes frostfs-cli to go through the list and HEAD for the object with --ttl 1, returning the list of nodes actually having the requested object.

Alternatives

We could do it by writing a script that takes placement vector for container and then loops over it with HEAD, but that's not very comfortable.

Either container nodes --oid or a separate object nodes seems legit.
I would go with a separate command -- it has different flags and works differently.
If needed, we can add networkless flag for HRW sort for object placement.
