Validation is the best time to return detailed diagnostics to the user since we're much more likely to have source location information, etc than we are in later operations. This change doesn't actually add any detail to the messages yet, but it changes the interface so that we can gradually introduce more detailed diagnostics over time. While here there are some minor adjustments to some of the messages to improve their consistency with terminology we use elsewhere.

The "backend" in Terraform defines how Terraform operates. The default
|
|
backend performs all operations locally on your machine. Your configuration
|
|
is configured to use a non-local backend. This backend doesn't support this
|
|
operation.
|
|
|
|
If you want to use the state from the backend but force all other data
|
|
(configuration, variables, etc.) to come locally, you can force local
|
|
behavior with the "-local" flag.
