调整puppet-service中的日志级别

[su-chang]

目前该项目中的日志级别极大部分都是verbose的，对于默认打印info级别日志的情况，排查某些问题会有不便。

如果将使用wechaty的默认日志等级调整为verbose会有很多冗余的puppet-service日志，影响日志的可读性。

因此需要将一些关键日志的等级做出调整。

An internal module should never print messages to users because it should be "just works". If it has to print something, it must be an error message because there's anything not expected, or we told it to output debug messages.

The PuppetService is an internal module, so it should not print any message by default.
log.info

Just imagine that, for the TCP/IP OSI layers, if every layer prints log messages to you, then it will be totally a mess.

A better way to achieve what you need, I believe is to add some events to the Brolog so that we can filter them.

For example:

log.on('verbose', (module, method, message) => {
  // filter module & method at here, and output whatever you want.
})

Should be able to be solved by huan/brolog#145

Stay tuned.
