8b3b16fe62 [#1825] writecache: Flush cache when moving to the DEGRADED mode 
Degraded mode allows us to operate without an SSD,
thus writecache should be unavailable in this mode.

ddaed283e9 [#1523] writecache: Simplify logic 
1. Remove in-memory cache. It doesn't persist objects and if we want
   more speed, `NoSync` option can be used for the bolt DB.
2. Put to the metabase in a synchronous fashion. This considerably
   simplifies overall logic and plays nicely with the metabase bolt DB
   batch settings.

73f8bb3e5f [#1523] shard: Store generic storage ID in metabase 
Allow to extend blobstor with more storage sub-systems. Currently
objects stored in the FSTree have empty byte slice descriptor and object
from blobovnicza tree have the same id as earlier. Each such change in
the identifier formation should be accompanied with metabase version
increase.

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.
