Azure Service Principal or Managed Identity authentication option for Trigger authentication in azure-pipelines scaler

[takis-kapas]

This affects the azure-pipelines scaler, specifically the "personalAccessTokenFromEnv: "AZP_TOKEN"" due to Microsoft's MFA enforcement mandate.

Microsoft is enforcing MFA for every account authentication, which will affect the Personal Access Token we have been generated for a service account and used in the "personalAccessTokenFromEnv: "AZP_TOKEN"" trigger for Azure Pipeline authentication.

Use-Case

Since we will no longer be able to sign-in to Azure DevOps Services (ADO) with an MFA-enabled service account to generate/update the PAT, are there any plans to include Service Principal or Managed Identity authentication (as an option) for the Trigger Authentication in azure-pipelines scaler?

Specification

• Service Principal authentication option in Trigger Authentication to Azure DevOps Services (azure-pipelines scaler)
• Managed Identity authentication option in Trigger Authentication to Azure DevOps Services (azure-pipelines scaler)
