504abdda06 [] shard: Exclude object.ErrAlreadyRemoved errors in refillMetabase
Tombstone and "alive" objects can be both stored in BlobStor. They can
appear during iterating in different order. Metabase returns
`ErrAlreadyRemoved` error if object is inhumed.

Ignore `object.ErrAlreadyRemoved` errors of `metabase.Put`in Shard's
`refillMetabase` operation.

b9c22e21b1 [] shard: Add method to refill the metabase
There is a need to refill Metabase data with the objects from BlobStor.

Implement `refillMetabase` method which iterates over all objects from
BlobStor and saves them in Metabase.

3f293cb55e [] storage/shard: Try to read headers from write-cache
Shard should try to read object headers from write-cache if it is enabled.

Extend `writecache.Cache` interface with `Head` method. Call the method in
`Shard.Head` if `Shard.hasWriteCache` returns true.

4da41613c3 [] shard: Initialize GC processes on Init
`Shard.Init` method creates a new GC instance from shard configuration and

13087dc3dd [] shard: Implement skeleton of internal GC
Shard's GC component consists of:
 * asynchronous remover that periodically wake up and removes all garbage
   objects from the shard, and goes to sleep for particular time interval;
 * external event listener that distributes jobs between workers;
 * group of workers that can handle a single job related to particular
   external event.

Remover and event listener represents go-routines which are started by
`init` method (calls from `Shard.Init`). In initial version all event
handlers are interrupted: this means that next event of the same type will
interrupt previous handling and start the new one.

GC is fully encapsulated in Shard. All GC configurations are reflected in
Shard's configuration.
