9c60ab893c [#1085] shard: allow to ignore errors during restore
We could also ignore errors during evacuate, but this requires
unmarshaling objects first which slowers the process considerably.

7eedb23eb7 [#1085] shard: allow to dump/restore objects
Dump contains magic and a list of objects prefixed by object size in bytes.
We can't use proto-marshaled list because this requires having all dump
in memory. Using TAR induces 512 byte overhead for each object which can
be a problem in some cases.

4da41613c3 [#378] shard: Initialize GC processes on Init

13087dc3dd [#378] 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.

b1718a60e4 [#176] shard: Fix BlobStor access when data range is zero
In previous implementation Shard accessed the BlobStor to get the
object header. However, the shard must take headers from the metabase.
From now zero length of the requested payload range seens as object
header request. In this case shard calls metabase to get the header.

df558cbe6b [#176] shard: Get rid of using the global RW lock
In previous implementation each shard operation locked
RW shard mutex. With this approach RW operations were executed
one-by-one and blocked the execution of RO operations.
