Is your feature request related to a problem? Please describe.

The problem is described in TrueCloudLab/frostfs-node#594
In short: when storage policy cannot be satisfied (REP 4 and one node in maintenance mode), delete operation will always fail.

Describe the solution you'd like

Delete operation produces tombstone object and puts it in nodes. Client can control number of acks from nodes with copies_number parameter of object put request. The same way it is possible to adopt copies_number or ack_number in the delete request with separate field or known x-header.

Describe alternatives you've considered

Return partial success status as it proposed in #33

The notion of "tombstone" already leaks outside, so I would rather use the exact same parameter name.
