> In this case we simply check HDFS for file existence, it returns false, and we exit immediately
without trying to remove a file from IGFS.
> Current approach offers better performance, but require all mutable interaction with
file system to happen through IGFS.
> Looks like we have to give user ability to choose between two options:
> 1) Better performance, but all goes through IGFS;
> 2) Worse performance, but all external changes do not break IGFS.
