…ervice to support automatic clusters (#2787)

## Description

Related to PR: Azure/azure-dev#4069

Adds new automatic setting for container service managed cluster.

Set `azure/login@v2` to use federated credential. (Due to some security
policies, we are currently unable to use client secret for azure login.
After completing all changes to this PR, we will restore the login
method. This is currently only for testing the github pipeline.)

The failed test in the Pipeline Status Badge has nothing to do with this
PR. The specific information can be viewed at:
