[Feature][Plugin] Add Grafana IRM Integration

リンクされている Grafana IRM Incident API と OnCall API のドキュメントから始め、利用可能なエンティティを DevLake の既存のデータソースプラグインのパターンと比較します。メンテナーがサポートする API とエンティティ、収集する範囲、同期戦略について合意した時点で、issue は次の段階に進められます。

Use case

Teams using Grafana Cloud IRM should be able to ingest its data into Apache DevLake and analyze it alongside data from other DevOps tools.

For example, incidents managed in Grafana IRM could be correlated with deployment data and used to calculate DORA metrics such as:

• Change Failure Rate
• Failed Deployment Recovery Time / MTTR

Description

I propose adding a grafana_irm data source plugin to support Grafana Cloud IRM.

Grafana IRM provides multiple capabilities, including Incident and OnCall, with APIs for programmatic access:

• Grafana IRM Incident API
• Grafana IRM OnCall API

For example, Grafana IRM Incident data could be mapped to DevLake's domain models as follows:

• Grafana IRM Incident → DevLake Issue (type = INCIDENT)
• Incident status → Issue status / original status
• Incident severity → Issue severity / priority
• Incident declared time → Issue created date
• Incident resolved time → Issue resolution date
• Incident roles/members → Issue assignees, where applicable

This could allow Grafana IRM incidents to be correlated with deployment data through DevLake's existing DORA incident-to-deployment correlation.

Before proceeding with the implementation, I would like to confirm whether this overall direction is appropriate, particularly regarding:

• which Grafana IRM APIs and entities should be supported
• the scope of data to be collected
• the synchronization strategy
