This commit implements the `buildserver shutdown` command that can be used to
shutdown MSBuild, VB/C# compiler, and Razor build servers.
By default, all three build servers are shut down. Options can be passed to
shut down a subset of the build servers.
Fixes#8185.
This commit implements the `uninstall tool` command.
The `uninstall tool` command is responsible for uninstalling global tools that
are installed with the `install tool` command.
This commit heavily refactors the ToolPackage and ShellShim namespaces to
better support the operations required for the uninstall command.
Several string resources have been updated to be more informative or to correct
oddly structured sentences.
This commit also fixes `--version` on the install command not supporting ranges
and wildcards.
Fixes#8549.
Issue #8485 is partially fixed by this commit (`--prerelease` is not yet
implemented).
