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.

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.

Close#1647.
Initially, `Sync: false` was provided because we can already lose
objects cached in memory. However, future changes in writecache will
remove inmemory cache and speed up it via other means.

Define `--with-attr` flag of `container list` which makes the command to
request and print user attributes for each found element.

If an object is found in the Write-cache and is placed at the end of
the in-memory cache, the memory counter update operation tries to
dereference the index that is out of the sliced array. Moreover, even if
panic does not appear, the counter is updated with the wrong value.

Return all the objects on the empty common prefix search without search
optimizations that breaks boltDB logic.

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.

Sort the endpoint by their priority before the first WS client creation to
start the morph client with the highest priority endpoint.

Handling notification in a synchronous manner may lead to a blocking state
if a handler uses neo-go client.

Return listen errors in a synchronous fashion.
Another solution would be to use buffered channel, but this is not
scalable: for each new similar runner we would need to extend the
buffer.

We have the default value which is also printed in the help messages but any
call that does not specify that flag leads to an error.

After a4adb79db new logical error could be returned. Do not increase
error counter in this case.
