Support multiple paths for diagnostics (#1616)

## Changes
Some diagnostics can have multiple paths associated with them. For
instance, ensuring that unique resource keys are used across all
resources. This PR extends `diag.Diagnostic` to accept multiple paths.

This PR is symmetrical to
https://github.com/databricks/cli/pull/1610/files
