Description

This PR changes the format of patterns. In detail, now patterns takes a pattern and constraints as an element. Here's an example:

version: "1"
rules:
  - id: test
    title: test
    tags:
      - low
    language: hcl
    message: "test"
    patterns:
      - pattern: |
          a = :[ATTR]
        constraints:
          - target: ATTR
            should: not-match-regex
            pattern: "^enabled$"
