Revert "Add stunnel container for Glance service"

This reverts commit 935adb59131caf66455a7d59c2af7cc42186e282.

It seems we cannot use stunnel on Ubuntu because
of no support for current OpenSSL. See [1].

We have some alternatives to replace stunnel:
- HAProxy (image ready; in progress)
- Apache2 (only embedded, no image)
- Nginx (possibly in the future)
