ba3db7fed5 [#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.

49c38d642d [#1902] engine: Search for the tree IDs in every shard
Iterate over every shard and search for the container's trees. Final result
is a concatenation of shards' results. It is considered that one fixed tree
is placed on one fixed shard but the different trees of a fixed container
could be placed on different shards.

8ffc2fdf5e [#1642] engine: Do not increase error counter if the pilorama is disabled
After a4adb79db new logical error could be returned. Do not increase
error counter in this case.

c7b10598f9 [#1333] engine: Increase error counter for pilorama errors
1. Modifying operations are not expected to fail, unless the shard is
   read-only.
2. `Get*` operations should increase error counter too, unless the
   error is `ErrTreeNotFound`.

8f4ee1aded [#1333] local_object_storage: Support ReadOnly mode in pilorama
The tricky part here is the engine itself: we stop iteration on
`ErrReadOnly` because it is better to synchronize the shard later than
to have partial trees stored in 2 shards.
