Rename functest-prepare role to prepare-tests

This change renames functest prepare-tole to prepare tests and makes other
adjustments to the role to move common test preparation steps to its own
script so we can prepare for Functest and Yardstick at one go.

Similar things are required to be prepared for running Functest and Yardstick
such as
- installed packages
- external network creation
- creation of run-functest.sh and run-yardstick scripts from templates
- preparation of environment variables

This change will fail verification until the changes below is submitted.
