dotnet-install should be able to get version from repository's global.json

Many users lock down their version of .NET Core via global.json. They also have scripts that prepare for build which installs the corresponding .NET Core. However, the version has to be defined in two places or every script must get the version from global.json and pass it to the dotnet-install script.

I’d like to add a feature to dotnet-install.ps1 to allow users to pass in a path to a global.json which will be read and that exact version will be installed. I’m not sure how to parse JSON in bash but I can try to update dotnet-install.sh as well.
