Cleanup spot instance distribution #603
Description
Description
Don't show instances that are too expensive in the spot instance distribution.
Motivation
If a user requests a p2.xlarge the distribution is [p2.xlarge, p3.2xlarge, p2.8xlarge], and the p2.8xlarge is a much more expensive instance which may not be worth if even if spot pricing is applied.
UPDATE: this may be less of an issue now that g3 and g4 instances are supported
