CORS-4057: migrate EC2 quota checking code AWS SDK v2

[tthvo]

Part of CORS-3819, this focuses on the quote checking code for EC2 instance types.

Note: This only upgrades code for fetching instance types during quota check. Full quote code upgrades to v2 is being tracked in CORS-4061.

Questions: User-provided service endpoints were never considered here. Is this intentional?
