downgrade App Service plan

[afeld]

We are currently using the PremiumV2 plan:

eligibility-server/terraform/app_service.tf

Line 6 in b1c8261

sku_name = "P2v2"

which is almost certainly more than we need, and thus a waste of money. More details.

This is the case in Benefits as well; asking DevSecOps about whether it's necessary.

Maybe we should have dev and test environments use the Free or Shared plan and have prod use Basic

I think the Basic plan meets our needs

App Service on Linux is not supported on Shared pricing tier.

From Param at DevSecOps, re: using PremiumV2 for Benefits:

We use Premium so that we get 20 instances to scale up in case needed, for all our Production environments. This also helps us create slots for lower environments in the same plan. Definitely you can go with the standard plan as we are going to have separate environments for Dev and Test. By the way standard plan gives us 10 instances which may be sufficient. Totally up to you.
