The direction bifrost roles are heading it may not make sense
to have secondary validation steps outside of the initial steps.
i.e. We should be attempting to validate we've completed x action
before leaving x action's steps. Separating them makes no sense.
As such, we're removing the un-necessary test step from the dynamic
test. Additionally noted the un-necessary nature and possibilites
in the node deployment given we can support users passing in their
own pre-formatted instance_info.
