Review Comment:
Actually, for the second option we changed the behavior by setting
`mountLinkGroupName` to `ugi.getPrimaryGroupName()` in the constructor, since
before we only set it on demand when we call `listStatus()`, `getFileStatus()`,
etc... Not sure this behavior change will cause other problems but this failed
some unit tests like `testListStatusWithNoGroups` with error "There is no
primary group for UGI" when we initialize `InternalDirOfViewFs`. Because in the
test we don't expect the error during filesystem initialization.
