It was needed before we started to flush during transition to
`degraded` mode. Now it is confusing.

Do not use node's local storage if it is clear that an object will be
removed anyway as a redundant. It requires moving the changing local storage
logic from the validation step to the local target implementation.
It allows performing any relations checks (e.g. object locking) only if a
node is considered as a valid container member and is expected to store
(stored previously) all the helper objects (e.g. `LOCK`, `TOMBSTONE`, etc).

It is not an error: removing virtual object is expected and should be just
skipped. Getting a virtual object with `raw` flag is considered as an
impossible action, all the virtual objects removals will be handled via
their children's removals implicitly.

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.

By default writecache puts the whole object to update storage ID.
This logic comes from the times when we needed to put objects
in the metabase by the writecache itself. Now this is done by the
blobstor at unmarshaling objects during flush only to update storage ID
is an overkill.

All logic errors are wrapped in `logicerr.Logical` type and do not
affect shard error counter.

In previous implementation node lost maintenance status after successful
switching to it. For example, after some period of time node sent
bootstrap requests with the "online" state instead of "maintenance".
Make `startMaintenance` method to set maintenance status in the
`networkState`.

In previous implementation bootstrapping state was chosen according to
bool flag which was not convenient.
Create separate method to boostrap with "online" and the current state.

In previous implementation `Shard.Delete` logged writecache's removal
failures in `error` level. There is a need to decrease severity of these
log records since they aren't critical and don't require individual
review.
Change level of the message to `info`.

Object removal session should reflect all objects related to the
removing one.
Make `OpenSessionViaClient` to gather the split members of the original
object in order to spread the session to them.
