Add support for Alibaba-Cloud EMR cluster template in alibaba provider

[EricGao888]

Description

• Alibaba Cloud EMR is an all-in-one enterprise-ready big data platform that provides cluster, job, and data management services based on open-source ecosystems, such as Hadoop, Spark, Kafka, Flink, and Storm.
• In airflow alibaba provider, we need to add support for Alibaba-Cloud EMR cluster template in alibaba provider so that users could use airflow operator to create / tear down EMR cluster automatically.

Use case/motivation

• Our team are using customized aliyun_emr_operator, which could create alibaba cloud EMR cluster based on existing template and tear it down when jobs on EMR are completed.
• With this feature, EMR cluster can be created when needed and torn down immediately after jobs on EMR completed so that user can save money cost by EMR machines.
• We'd like to contribute this feature to airflow community.
