There should be support to easily choose the name of the binary log

Opening at request of https://github.com/dotnet/arcade/pull/1972#pullrequestreview-199839802

Our repository calls build.ps1 during multiple phases in the same job. during CI. We would like a way to easily name the resulting binary log. We do this in order to separate out the build steps to be more modular and clean. See the example below

       # Build
       - script: eng\cibuild.cmd
          -prepareMachine
          -configuration $(_BuildConfig)
          $(_OfficialBuildIdArgs)
          -build
        displayName: Build

      # Run unit tests
      - script: eng\cibuild.cmd
          -configuration $(_BuildConfig)
          $(_OfficialBuildIdArgs)
          -test
        displayName: Run Unit Tests

      # Create Nuget package, sign, and publish
      - script: eng\cibuild.cmd
          -configuration $(_BuildConfig)
          -bl SignPackPublish
          $(_OfficialBuildIdArgs)
          -sign $(_SignArgs)
          -publish $(_PublishArgs)
        displayName: Pack, Sign, and Publish

We do not wish to change the way we are building to call build.sh instead (see workaround https://github.com/dotnet/arcade/blob/master/azure-pipelines.yml#L133)

I disagree. Please follow Arcade guidelines and build everything in one step. We are not gonna support this pattern. Adding support for this build pattern increases complexity of Arcade and thus the cost of maintenance and testing. It also makes it harder to work with multiple repos if they each decide to use a different approach to build.

NuGetCommand@2 doesn’t use dotnet cli. It uses NuGet.exe that’s provided by the Pipelines Task.
