Earlier, we were not configuring the end_date while creating
a fixed-price plan which would result in the automatic renewal
of the plan at the end of billing cycle.
Our plan is to re-evaluate the pricing when we are close to the
end date, then:
1. Schedule a new fixed-price plan with the updated or same price.
2. or Don't do anything - the plan will end on the end_date.
Now, we add an end_date of 1 year from the start date when
creating a fixed-price plan.
