Terraform login prompt should require `yes` for approval

Current Terraform Version

0.12.21+

Use-cases

The terraform login command requires acceptance to proceed.

Currently, acceptance of the login workflow requires a y input on the CLI. The prompt is currently y/n. This is inconsistent with Terraform's current approval prompt which requires an explicit yes.

Proposal

Alter the approval of terraform login to yes. This would be consistent with current workflows.

If Terraform Login is being used in automation this is a breaking change.

Why does this have to be a breaking change? Couldn't you update both prompts to accept either y or yes (case in-sensitive), and still get consistent behavior?

@mmmorris1975 Great question!

Terraform prompts (save for this login one) don't allow for input of y or n responses. This is about consistency of workflow across the tool. We don't intend to add short versions of other responses at this time and so breaking change it is.

We should have caught it sooner.
