 1 client ： 模块，python处理salt-api的主要模块，‘client interfaces <netapi-clients>’
 2     local : 使用‘LocalClient <salt.client.LocalClient>’ 发送命令给受控主机，等价于saltstack命令行中的'salt'命令
 3     local_async : 和local不同之处在于，这个模块是用于异步操作的，即在master端执行命令后返回的是一个jobid，任务放在后台运行，通过产看jobid的结果来获取命令的执行结果。
 4     runner : 使用'RunnerClient<salt.runner.RunnerClient>' 调用salt-master上的runner模块，等价于saltstack命令行中的'salt-run'命令
 5     runner_async : 异步执行runner模块
 6     wheel : 使用'WheelClient<salt.wheel.WheelClient>', 调用salt-master上的wheel模块，wheel模块没有在命令行端等价的模块，但它通常管理主机资源，比如文件状态，pillar文件，salt配置文件，以及关键模块<salt.wheel.key>功能类似于命令行中的salt-key。
 7     wheel_async : 异步执行wheel模块
 8     备注：一般情况下local模块，需要tgt和arg(数组)，kwarg(字典)，因为这些值将被发送到minions并用于执行所请求的函数。而runner和wheel都是直接应用于master，不需要这些参数。
 9 tgt : minions
10 fun : 函数
11 arg : 参数
12 expr_form : tgt的匹配规则
13     'glob' - Bash glob completion - Default
14     'pcre' - Perl style regular expression
15     'list' - Python list of hosts
16     'grain' - Match based on a grain comparison
17     'grain_pcre' - Grain comparison with a regex
18     'pillar' - Pillar data comparison
19     'nodegroup' - Match on nodegroup
20     'range' - Use a Range server for matching
21     'compound' - Pass a compound match string
