[CLI] Introduce rally db <command>

Having 2 entrypoint seems redudant and complicated for end users,
so instead of rally-manage db <commands> let's use rally db <commands>

This reduces amount of code and commands needed to know to work with
Rally which is actually good.

This patch doesn't remove rally-manage just deprecates it
