* [entraid] add setup script for offline clusters.
This PR adds a cli configuration for Entra ID where it's possible to default to system credentials instead of relying on OIDC for authentication in EntraID. OIDC is not always a possibility specially when the cluster is private and not internet acessible.
The UX is the following:
```text
Step 1: Run the Setup Script
1. Open **Azure Cloud Shell** (Bash) using **Google Chrome** or **Safari** for the best compatibility.
2. Upload the setup script using the **Upload** button in the Cloud Shell toolbar.
3. Once uploaded, execute the script by running the following command:
$ bash entraid.sh
**Important Considerations**:
- You must have **Azure privileged administrator permissions** to complete the integration.
- Ensure you're using the **Bash** environment in Cloud Shell.
- During the script execution, you'll be prompted to run 'az login' to authenticate with Azure. **Teleport** does not store or persist your credentials.
- **Mozilla Firefox** users may experience connectivity issues in Azure Cloud Shell; using Chrome or Safari is recommended.
Once the script completes, type 'continue' to proceed, 'exit' to quit: continue
Step 2: Input Tenant ID and Client ID
With the output of Step 1, please copy and paste the following information:
Enter the Tenant ID: 1056b571-0390-4b08-86c8-2edba8d9ae79
Enter the Client ID: 1056b571-0390-4b08-86c8-2edba8d9ae79
Successfully created EntraID plugin "name".
