Fix for version comparison from strings to semver (#4608)

* Fix for version comparison from strings to semver

See #3002 for more detail

* Include pre-releases in the semver ranges

This is important when testing against alpha and beta builds of
Kubernetes along with environments that use pre-releases to denote
things other than pre-releases (e.g., gke denotes the environment
with a pre-releases)
