ansible-playbook error: Failed to connect to the host via ssh: ControlPath too long

参考： https://stackoverflow.com/questions/33516218/ansible-ssh-error-controlpath-too-long/33516873

解决方法：

在ansible.cfg配置文件中，添加：

[ssh_connection]
ssh_args =

该命令将会覆盖默认配置，将ControlMaster/ControlPersistent/ControlPath的配置值置为空。
