Remove molecule dependencies (#261) (#263)

Remove molecule dependencies

SUMMARY

Depends-on: ansible-collections/cloud.common#92
Molecule is overwriting the cloud.common dependency installed by zuul,
which is causing issues with the CI job for turbo mode. We still need to
find a way to test against the latest released version of cloud.common.
