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.

fcdbf5e509 [#1969] local_object_storage: Add a type for logical errors
All logic errors are wrapped in `logicerr.Logical` type and do not
affect shard error counter.

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.
