+`goodcheck.yml` can have optional `import` attribute.

+```yaml
+rules: []
+import:
+  - /usr/share/goodcheck/rules.yml
+  - lib/goodcheck/rules.yml
+  - https://some.host/shared/rules.yml

+- A string which represents an absolute file path,
+- A string which represents an relative file path from config file, or
+- A http/https URL which represents the location of rules
