> In container-executor.c, delete_path() returns early when unlink() against a file or
a symlink fails. We have seen many cases of the error being ENOENT, which can safely be ignored
during delete.  
> This is what we saw recently: An app mistakenly created a large number of files in the
local directory and the deletion service failed to delete a significant portion of them due
to this bug. Repeatedly hitting this on the same node led to exhaustion of inodes in one of
the partitions.
> Beside ignoring ENOENT,  delete_path() can simply skip the failed one and continue in
some cases, rather than aborting and leaving files behind.
