Issue description

There are 2 issues for the plugin code(not bin/analyzer). Currently, it is not a bug but nice to have

1. BundleAnalyzerPlugin.js should use InfrastructureLogger from webpack compiler. When I run my jest test, there are some noise message from the plugin. See the following screenshot.
   
   I can silent theconsole.log for my jest test. But I have to write some to find the plugin in my sharedwebpack.config.js and then replace the existing plugin with another one to silent log messages.
2. When I launch the webpack-dev-server, I expect mydist should be empty. Currently it always has report.html. Other assets are in memfs. I have a jest test to check the folder is empty. Now I have to write more code to handle it differently
