Reusable ingress/egress rule templates for security groups

### The required feature described as a wish

Problem: There is currently no way to save or reuse common ingress/egress rule sets across security groups. Every new security group requires rules to be manually re-entered one by one through the UI

Requested behavior: allow users to define and save named rule templates. For instance "baseline-access", "web-server", "database", with options to define specific ports needed. When creating a new security group, allow selection of one or more templates to pre-populate rules

先定位 security-group 建立的進入點，以及現有的 ingress/egress 規則模型和 API。追蹤規則如何輸入和持久化，然後找出涵蓋 security-group 建立的測試；完成的標準是可以儲存具名範本、單獨或組合選取這些範本，並使用它們以指定的連接埠預先填入規則。
