## Changes
The APIs at Databricks when returning a non `200` status code will
return a response body of the format:
```
{
"error_code": "Error code",
"message": "Human-readable error message."
}
```
This PR adds the ability to stub non-200 status codes in the test
server, allowing us to mock API errors from Databricks.
## Tests
New test
## Changes
With this PR, any acceptance tests that define custom server stubs in
`test.toml` will automatically record all HTTP requests made and assert
on them.
Builds on top of https://github.com/databricks/cli/pull/2226
## Tests
Modifying existing acceptance test.
## Changes
This PR registers the `server.Close()` function to be run during test
cleanup in the server initialization function. This ensures that all
test servers are closed as soon as the test they are scoped to finish.
Motivated by https://github.com/databricks/cli/pull/2255/files where a
regression was introduced where we did not close the test server.
