New Resource: alicloud_alidns_cloud_gtm_monitor_template.

[LCLSpring]

Summary

Adds alicloud_alidns_cloud_gtm_monitor_template — a reusable Cloud GTM health-check probe template (protocol / interval / failure thresholds / probe nodes) that can later be attached to Cloud GTM address pools.

What's in the PR

• Resource (alicloud/resource_alicloud_alidns_cloud_gtm_monitor_template.go) — full Create / Read / Update / Delete / Import lifecycle.
• Service layer (alicloud/service_alicloud_alidns_v2.go) — DescribeAlidnsCloudGtmMonitorTemplate + state-refresh helpers.
• Registration in alicloud/provider.go.
• Acceptance tests — 4 cases covering the attribute matrix across ping / tcp / http / https protocols and IPv4 / IPv6: basic12684, basic12685, basic12690, basic12691.
• Documentation (website/docs/r/alidns_cloud_gtm_monitor_template.html.markdown) — written to render cleanly on the Terraform Registry and aligned with the actual schema:
  • isp_city_nodes labelled (Required, Set) to match schema.TypeSet.
  • Enum values match schema validators (evaluation_count: 0/1/2/3; failure_rate: 0/20/50/80/100; interval: 15/60/300/900/1800/3600; timeout: 2000/3000/5000/10000).
  • extend_info documented as a dedicated section split by protocol (http/https, ping, tcp) so the nested JSON fields render as proper GFM lists on the Registry.
  • extend_info labelled (Optional, Computed) to match Computed: true in the schema.

Test plan

• IntegrationTest CI job passes all 4 acceptance cases
• DocsExampleTest CI job passes (init → plan → apply → no-drift → import → apply import plan → destroy)
