[Hubs] Troubleshooting tool

📝 Scenario

As a FinOps hub admin, I need to identify and resolve common issues in order to get my hub in a healthy state

💎 Solution

Create a troublehsooting tool that can identify problems and recommend solutions to those problems.

This may require creating other commands to test various aspects of the account, like validating private endpoints or access to storage.

### Ideas to consider
- [ ] Give instructions for how to download/configure Power BI reports with specific values
- [ ] Does the storage account have a firewall enabled?
- [ ] Include networking details + validate connectivity + recommend fixes for connectivity issues
- [ ] Implement all processes and checks from the troubleshooting guide
- [ ] Suggest what team should help with issues for Microsoft Support routing
- [ ] Confirm the event hub resource provider is registered
- [ ] Confirm the triggers have started in ADF
- [ ] Collect any errors from ADF logs
- [ ] Look up errors in ADX (especially ingestion failures)
- [ ] Look up template deployment errors
- [ ] Look up errors against documentation to determine if there are known resolution steps
- [ ] Are there any failed pipeline runs in the last 7 days that were not re-run?
- [ ] Consider adding SLA metrics, like perf and reliability

No files, tests, or command entry points are named. Start by reading the referenced troubleshooting guide and comparing it with the listed checks across storage, networking, ADF, ADX, Event Hubs, and template deployments; the scope and completion criteria need to be defined before implementation.
