Look up a directory entry by name and get its attributes.
This method should return an EntryAttributes instance for the directory entry name in the
directory with inode parent_inode.
If there is no such entry, the method should either return an EntryAttributes instance with
zero st_ino value (in which case the negative lookup will be cached as specified by
entry_timeout), or it should raise FUSEError with an errno of errno.ENOENT (in this case
the negative result will not be cached).
ctx will be a RequestContext instance.
The file system must be able to handle lookups for . and .., no matter if these entries are
returned by readdir or not.
(Successful) execution of this handler increases the lookup count for the returned inode by one.
