是否有任何选项可自定义电子邮件并在DAG中发送任何任务失败。有一个类似'email_on_failure'的选项：True，但这不提供将内容动态添加到电子邮件主题或正文的选项。

我的DAG如下所示

import airflow

from airflow import DAG
from airflow.contrib.operators.databricks_operator import DatabricksSubmitRunOperator
from airflow.operators.email_operator import EmailOperator
from airflow.operators.bash_operator import BashOperator
from airflow.operators.http_operator import SimpleHttpOperator
from airflow.operators.sensors import HttpSensor
import json
from datetime import timedelta
from datetime import datetime
from airflow.models import Variable

args = {
    'owner': 'airflow',
    'email': ['test@gmail.com'],
    'email_on_failure': True,
    'email_on_retry': True,
    'depends_on_past': False,
    'start_date': airflow.utils.dates.days_ago(0),
    'max_active_runs':10
}

dag = DAG(dag_id='TEST_DAG', default_args=args, schedule_interval='@once')

new_cluster = {
    'spark_version': '4.0.x-scala2.11',
    'node_type_id': 'Standard_D16s_v3',
    'num_workers': 3,
    'spark_conf':{
        'spark.hadoop.javax.jdo.option.ConnectionDriverName':'org.postgresql.Driver',
        .....
    },
    'custom_tags':{
        'ApplicationName':'TEST',
        ..... …
