There are some "well-known" headers starting with `__SYSTEM__` prefix that
affect system behaviour. For backward compatibility, the same set of
"well-known" headers may also use `__NEOFS__` prefix:
* `__FROSTFS__NETMAP_EPOCH` - netmap epoch to use for object placement calculation. The `value` is string
* `__SYSTEM__NETMAP_EPOCH` - netmap epoch to use for object placement calculation. The `value` is string
encoded `uint64` in decimal presentation. If set to '0' or omitted, the
current epoch only will be used.
* `__FROSTFS__NETMAP_LOOKUP_DEPTH` - if object can't be found using current epoch's netmap, this header limits
* `__SYSTEM__NETMAP_LOOKUP_DEPTH` - if object can't be found using current epoch's netmap, this header limits
