logger name for execution events should not be MavenCli

actually, a lot of Maven output is done with MavenCli logger even 3 times the code executed is not in MavenCli. See the MavenCli code:
1. CLIReportingUtils.showErrors
2. ExecutionEventLogger
3. getBatchTransferListener()
If it can make sense to have the first one reporting with MavenCli logger name, the 2 formers whould better be with their own logger: this would ease filtering
