[enhancement](spark-load)support dynamic set env

[chenlinzhong]

Proposed changes

Issue Number: close #xxx

Problem summary

Fe submits tasks to spark through the spark submit client, which needs two environment variables Hadoop_ user_ name hadoop_ user_ The two variables password do not support dynamic settings now. I want these two variables to support dynamic settings so that different jobs can be submitted with different accounts

fe通过spark-submit客户提交任务到spark，这个客户端需要两个环境变量hadoop_user_name hadoop_user_password 这两个变量现在不支持动态设置，我想要这两个变量支持动态设置，这样不同的job可以使用不同的账号来提交

前缀为env. 开头的变量为环境变量，hadoop认证方式不是simple的不用填

CREATE EXTERNAL RESOURCE "test_env"  PROPERTIES(
 "type" = "spark",
 "spark.master" = "yarn",
"spark.executor.memory"="8g",
"spark.master"="yarn",
"spark.driver.extraLibraryPath"="/usr/lib/hadoop/lzo/lib:/usr/lib/hadoop/lib/native",
"env.HADOOP_USER_NAME"="user",
"env.HADOOP_USER_PASSWORD"="password"
);
