Support (and or document) silent install/uninstall

[DavidBoike]

Describe the feature.

Support doing silent installs and uninstalls of ServiceInsight.

This will currently work from an elevated prompt to silently install, as the /qn parameter is passed along to the MSI process internally:

ServiceInsight-2.13.0.exe /qn

Using info from https://www.silentinstall.org/msiexec a silent install that dumps the install log out to a specific location can also be accomplished.

But this is undocumented.

A silent uninstall doesn't seem to be possible at this point.

Additional Context

A customer told me that they use Microsoft Intune for managing devices/installing programs, and silent install/uninstall is needed for this.
