This change removes a check that denies the creation of a pool
if the new pool has the same image and flavor set on the same
provider. The reasoning for that check was that if you need to
create another pool with identical settings to an existing one,
you might as well scale up the min-idle-runners on the old one.
This was done when runner groups were not yet added. This in
turn has forced users to alias images with new names in their
provider, leading to terrible UX. In the end, being too
opinionated in this case has caused more harm than good.
