feat(azure): Add shared tag support to Function Apps, Logic Apps, Loa…

[janithashri]

Summary

This pull request expands the shared Azure Tag ingestion pattern to four additional services: Function Apps, Logic Apps, Load Balancers, and Monitor.

This PR also standardizes error handling in these modules to match the project's new pattern (fail loudly on auth errors, handle transient errors gracefully).

• New Relationships:
  • (AzureFunctionApp)-[:TAGGED]->(AzureTag)
  • (AzureLogicApp)-[:TAGGED]->(AzureTag)
  • (AzureLoadBalancer)-[:TAGGED]->(AzureTag)
  • (AzureMonitorMetricAlert)-[:TAGGED]->(AzureTag)

Description

1. Function Apps: Added AzureFunctionAppTagsSchema and updated sync logic to load tags (filtering out Web Apps).
2. Logic Apps: Added AzureLogicAppTagsSchema, updated sync logic, and fixed transformation to include tags.
3. Load Balancers: Added AzureLoadBalancerTagsSchema and updated sync logic.
4. Monitor: Added AzureMonitorMetricAlertTagsSchema for metric alerts.
