Support muti-level logger in azd

[rujche]

For current azd, the logger only has one level: output or not output.

1. Without "--debug" program parameter, there is no output. Customer will lack necessary information.
2. WIth "--debug" program parameter, there will be too much (hundreds or even thousands of lines) logs.

It's a reasonable request to support multi-level log in azd. Here are common used levels: info, warn, error.

And I found loggers for go lang:

1. https://github.com/sirupsen/logrus
2. https://github.com/uber-go/zap
