• test_porxy integ test can not pass on Jenkin but can pass on local machine, suspect is because of SSH settings on Jenkins docker

• Fix Proxy Stack deletion failed issue
• For Paramiko : Error reading SSH protocol banner issue, tried below options:
  • Increase banner_timeout
  • Run ssh-agent -s and set the env variables, run ssh-add <private-key>
    • Modify run_command function, if env is not set, use os.environ
  • Enable inline_ssh_env for RemoteCommandExecutor, and add env_prefix before the commands
