Bump deprecation in win_servermanager state to Neon
Bump deprecation in win_servermanager state to Neon

The original deprecation notice says the "force" option in
win_servermanager.installed will be removed in Fluorine. However, this change
was recenlty made in 2018.3.0. We need to give 2 feature releases before
removal.
