Expected Behavior

"An execution plan has been generated and is shown below."

Actual Behavior

Crash

Steps to Reproduce

1. terraform init
2. terraform plan

Additional Context

The features {} block is an azurerm v2.0 feature. I had accidently left it in the provider section. Terraform misses this, and passes it along to the azurerm provider which causes it to crash.
Terraform should be catching this and throwing an error.
