fdeea1dfac [#2057] meta: Fix concurrent mode changes
Includes:
1. mode change read lock operation in every exported method that r/w the
underlying database;
2. returning `ErrDegradedMode` logical error if any exported method is
called in degraded (without a metabase) mode.

634792077e [#1502] node: Store lock object on every container node
Includes extending listing methods in the Storage Engine with object types.
It allows tuning replication/policer algorithms: container nodes do
not remove `LOCK` objects as redundant and try to fulfill `LOCK` placement
on the ohter container nodes.

2849e465f9 [#1699] meta: Do not return SplitInfoError on Delete
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.

5cf75404dc [#1818] metabase: Add UpdateStorageID operation
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.

In the 2nd version, there was a database format change: buckets have changed

migrations because of different buckets that store info about the version.

ad47e2a985 [#1658] meta: Add logic counter
- Meta now supports (and requires) inc/dec labeled counters
- The new logic counter is incremented on `Put` operations and is
decremented on `Inhume` and `Delete` operations that are performed on
_stored_ objects only
- Allow force counters sync. "Force" mode should be used on metabase resync
and should not be used on a regular meta start

Allow to extend blobstor with more storage sub-systems. Currently

from blobovnicza tree have the same id as earlier. Each such change in

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.

`Degraded` mode can be set by the administrator if needed.
Modifying operations in this mode can lead node into an inconsistent state
