When node put chunk into EC container, `policer` may remove it as redundant.
This chunk marked as removed. When parent object removed and `gc` start iterating over chunk,
node count removing chunk twice.

EC parent and split gc marks should be deleted after last EC chunk delete.
Also should delete split info for EC parent and split parent.

It is required to save split parent ID too, not only split ID.
Otherwise inhume operation works incorrect: shard with last part may be skipped
and parent object will be available.

For REP updating split info is handled explicitly by a high-level PUT logic.
For EC it is trickier, because the address of an object we put is only
distantly related to a split info.

* If EC-parent is a part of Split itself, then save to root bucket
its parent;
* If EC-parent is not a part of Split itself, then save to root bucket
OID of this EC-parent.

* `GetECHeader` is not correct way to determine if an object's got
EC-header: `ECHeader` must be used for that.

metabase.Open() now reports metabase mode metric. shard.UpdateID()
needs to read shard ID from metabase => needs to open metabase.
It caused reporting 'shard undefined' metrics. To avoid reporting
wrong metrics metabase.GetShardID() was added which also opens
metabase and does not report metrics.

It used to always show CLOSED regardless of actual mode.
Now metric represents actual metabase mode of operations.

There may be a race condition between put an object and
flushing the writecache:
1. Put object to the writecache
2. Writecache flushes object to the blobstore and sets blobstore's
storageID
3. Put object to the metabase, set writecache's storageID

Most of the time it exits, e.g. when it is per-container and use on each
object PUT. Bbolt implementation first tries to create bucket and then
returns it if it exists. Create operation uses cursor and thus is not
very lightweight, we can avoid it.

GC inhumes expired locks and tombstones on all the shards.
So it could be GC mark without object.
