.DESCRIPTION
Reads $RepoRoot\global.json file to determine native assets to install
and executes installers for those tools

.PARAMETER BaseUri
Base file directory or Url from which to acquire tool archives

.PARAMETER InstallDirectory
Directory to install native toolset.  This is a command-line override for the default
Install directory precedence order:
- InstallDirectory command-line override
- NETCOREENG_INSTALL_DIRECTORY environment variable
- (default) %USERPROFILE%/.netcoreeng/native

.PARAMETER Clean
Switch specifying to not install anything, but cleanup native asset folders

.PARAMETER Force
Clean and then install tools

.PARAMETER DownloadRetries
Total number of retry attempts

.PARAMETER RetryWaitTimeInSeconds
Wait time between retry attempts in seconds

.PARAMETER GlobalJsonFile
File path to global.json file
