Azat Khuzhin 324b1a7658 Add server UUID for the S3 disks checks to avoid possible races 
Otherwise, if you are lucky enough, race condition is possible, and you
can get some errors because one server already removed the file while
another was trying to read it.

But it was possible only for:
- batch deletes check for "s3" disk
- and all checks for "s3_plain" disk, since this disk does not uses
  random names
