Pricing info for EMR

Issue

• When designating --service emr , the prices reflect EC2 On-demand costs:
  • ex: m5.12xlarge returns $2.304

Expected Behavior

• Price should reflect EC2 on-demand costs plus the EMR premium from the emr pricing table
• From the pricing table, the EMR premium for m5.12xlarge is $0.27/hr, so the output should be $2.304+$0.27 = $2.574
