Remove support for opensuse

We haven't been testing the distro for a while in CI, e.g. in
Tempest, the jobs on opensuse15 haven't been executed for a year
now.
Therefore the patch removes opensuse support from devstack.

Closes-Bug: #2002900

 Although there a no plans to remove this method of installing
 packages, plugins should consider it deprecated for ``bindep`` support
 described below.
