Remove version checks

openstacksdk 1.0.0 was released 3½ years ago [1]. pip is not going to
pull that version any more. These checks are redundant.

In addition, we can remove sdk_version extra var. Change
I9665f04e6c0d5a84d6c20a73ef7b0dfdc7bd8159 removed the last guard that
relied on this, similarly about 3½ years ago.
