Issue 911814: [Remoting Windows] Can't reinstall host

Reported by, Dec 4 Project Member

Issue description

In some cases we'd like the user to be able to reinstall the host by rerunning the MSI file, say the user had deleted the host service manually and they need to reinstall to repair. User currently can fix that by installing a newer host version, but rerunning the MSI with the current host version doesn't do anything.

OTOH rerunning installers on Mac and Linux works and fixes issues caused by broken components.

[Remoting Windows installer] Set REINSTALL and REINSTALLMODE properties for reinstallation

We saw a few users having problem starting the host because the host service
has been removed while the native messaging host is still there. On other
platforms this can be fixed by reinstalling the host, but rerunning the MSI on
Windows does nothing unless it's an upgrade.

This CL adds the REINSTALL and REINSTALLMODE properties to the installer if the
user tries to rerun the MSI, so that the installer will forcibly reinstall all
files and services.

Hi Yuwei, All done and worked great. Some of the host version numbering doesn't match, between the download links and references in the doc. I used the versions linked for download. Let me know if those are not correct.

Thank you AJ! 3658 and 3660 are M73 builds so I just mislabeled them :P
