In current implementation, Job manager writes task manager configuration into a file and upload it to HDFS. This file's used to bootstrap taskmanager.
In this PR, it switches to use system environment instead of HDFS file to pass the configuration from job manager to task manager, which reduce the dependency on HDFS.
