I'm mostly okay with it, though the deployment plan isn't the proper place for what's essentially a referral code.

Hashicorp is facilitating the purchase of Azure products, and deserves a cut of the revenue. But this should be handled on the account level, either on sign-up or as an account field (a-la Amazon Smile)

I'm less okay with the tracking for analytics purposes, but if Terraform finds some way to make it easy for me to tell cloud providers who sent me, that seems fair.
