b1718a60e4 [] 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 [] 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.
