Allow specifying tags during sidecar install on windows

[drewmiranda-gl]

With the introduction of tags for Graylog 5 and Sidecar 1.3, it would be helpful to specify tags as an installer argument. I believe the original sidecar tags worked this way but can't recall.

This makes sense because tags are meant to be for automation, however we don't provide a[n easy] way to configure these. It is certainly possible to use a sed style script or powershell command but that adds some extra complexity and has a much higher skill floor than running an automated install with arguments.
