Split Yardstick CLI with Yardstick core logic

JIRA: YARDSTICK-511

We need to unify yardstick entry. Now the solution is using CLI call API
as nova do.
This is the first step: coupling the yardstick core logic from CLI.
Moving the core logic to yardstick/benchmark/core and the CLI using a
object to call yardstick core logic.
