FrostFS client sometimes can't store all required copies when some storage nodes are unavailable in container (e.g. in maintenance mode). In this case internal error is returned with incomplete object put message. However this does not mean that put operation was completely failed. Some nodes will store object, just less acks received than expected.

Describe the solution you'd like

Introduce new error status when operation was partially successful. Add details with the number of successful acks in status details. In some cases clients will be just fine with partial success.

Describe alternatives you've considered

Keep it as it is and use copies number parameter more often.

The problem is that every failed PUT is "incomplete" in some sense.
I suggest reserving this status for cases when there was at least 1 or at least 1 non-local success.
