[Feature Request] enhance error messages

[Tony-Proum]

Terraform Version

Terraform v0.14.2

Terraform Configuration Files

provider "opsgenie" {
  api_key = "test"
}

Expected Behavior

Terraform plan should write a clear message that allows to quickly figure out what' s going wrong

Actual Behavior

we got a runtime error:

Error: Error occurred with Status code: 422, Message: Key format is not valid!, Took: 0.001000, RequestId: <any-id>

this message is a bit cumbersome and does not allows to understand what's wrong with our configuration, mainly when we have to deal with multiple providers that use some keys as well.

Still an open issue:

❯ terraform --version
Terraform v1.1.3
on linux_amd64
+ provider registry.terraform.io/opsgenie/opsgenie v0.6.8

This is beginning to affect our projects as well.
