47e8c5bf23 [#156] pilorama: Remove CIDDescriptor from TreeApply()
Initially it was there to check whether an update is being initiated by
a proper node. It is now obsolete for 2 reasons:
1. Background synchronization fetches all operations from a single node.
2. There are a lot more problems with trust in the tree service, it is
   only used in controlled environments.

b4e90cdf51 [#2165] pilorama: Optimize TreeApply when used for synchronization
Because synchronization _most likely_ will have apply already existing
operations, it is much faster to check their presence in a read
transaction. However, always doing this will degrade the perfomance
for normal `Apply`. And, let's be honest, it is already not good.
Thus we add a separate parameter which specifies whether this logic is
enabled.

d8d3588e1b [#1996] engine: Always select proper shard for a tree
Currently there is a possibility for modifying operations to fail
because of I/O errors and a new tree to be created on another shard.
This commit adds existence check for modifying operations.
Read operations remain as they are, not to slow things.
`TreeDrop` is an exception, because this is a tree removal and trying
multiple shards is not an unwanted behaviour.

b064fb24d8 [#1616] engine: Do not use batches in delete
Use a simple loop at the callsite. This way we remove as much as we can.
Also, `Delete` metrics is more meaningful now.

156ba85326 [#1634] node: Do not return expired objects
If an object has not been marked for removal by the GC in the current epoch
yet but has already expired, respond with `ErrObjectNotFound` api status.
Also, optimize shard iteration: a node must stop any iteration if the object
 is found but gonna be removed soon.
All the checks are performed by the Metabase.

4944490ffb [#1559] local_object_storage: Move shard to the DegradedReadOnly mode
`Degraded` mode can be set by the administrator if needed.
Modifying operations in this mode can lead node into an inconsistent state
because metabase checks such as lock checking are not performed.

e38b0aa4ba [#1549] engine: Disable shard on blobovnicza init failure
There is a need to support working w/o shard if it has problems with
blobovnicza tree.

Make `BlobStor.Init` to return new `ErrInitBlobovniczas` error. Remove
shard from storage engine's shard set if it returned this error from
`Init` call. So if some of the shards (but not all) return this error,
the node will be able to continue working without them.

The tricky part here is the engine itself: we stop iteration on

to have partial trees stored in 2 shards.
