ACLP Alerting go SDK

[srbhaakamai]

📝 Description

Provide go SDK support to ACLP clients to perform CRUD operations for Alerts.

✔️ How to Test

How do I run the relevant unit/integration tests?

Prerequisites
Go 1.19+ installed
Valid Linode API token with monitor permissions
Export LINODE_TOKEN environment variable for integration tests

Run all monitor alert definition unit tests:
UNIT TEST:
go test ./test/unit -run ".MonitorAlertDefinition." -v

Expected Output:

✅ TestCreateMonitorAlertDefinition
✅ TestCreateMonitorAlertDefinitionWithIdempotency
✅ TestGetMonitorAlertDefinition
✅ TestListMonitorAlertDefinitions
✅ TestUpdateMonitorAlertDefinition
✅ TestUpdateMonitorAlertDefinition_LabelOnly
✅ TestDeleteMonitorAlertDefinition

INTEGRATION TEST:
export LINODE_TOKEN="your-linode-api-token"
go test ./test/integration -run "TestMonitorAlertDefinition_smoke" -v

Test Coverage:

List Operations: Validates fetching existing alert definitions
Channel Discovery: Finds available alert channels for testing
Create: Tests complex alert definition creation with:
TriggerConditions (evaluation periods, polling intervals)
RuleCriteria with Rules (metrics, operators, thresholds)
DimensionFilters (node type filtering)
Update: Tests label-only updates with proper timing
Delete: Tests cleanup with exponential backoff retry logic
Expected Duration: ~102 seconds (includes API timing requirements)
