Docker image is missing NPM, grunt-cli and Git

[queue-b]

When attempting to build a docker image, the command kpm restore fails when run on an ASP.net vNext project directory generated by Visual Studio 2015.

Command output:

System.ComponentModel.Win32Exception: ApplicationName='npm', CommandLine='install', CurrentDirectory='/usr/src/app/src/Botlink.Api.Server', Native error= Cannot find the specified file

This is due to the base image missing NPM. Once NPM is installed, the error becomes

System.ComponentModel.Win32Exception: ApplicationName='grunt', CommandLine='bower:install', CurrentDirectory='/usr/src/app/src/Botlink.Api.Server', Native error= Cannot find the specified file

which indicates that grunt-cli cannot be found. Once grunt-cli is installed, process finishes sucessfully, but there is a complaint by bower that git is missing.

Running "bower:install" (bower) task
Fatal error: git is not installed or not in the PATH

I have a working dockerfile that adds the three tools; I would gladly contribute my changes to aspnet-docker if this is actually an issue and not a deliberate design decision. I would argue that if kpm restore against a Visual Studio project expects NPM, grunt-cli, and git to be installed, they should probably be installed by default in the docker image.
