Improve windows installer

[v-zhuravlev]

During interactive windows installer, we can only enable windows_exporter on/off. So agent is not fully functional after agent setup, as it is not sending data anywhere. Config has to be updated anyway.

Since some of our users will be installing agent in interactive mode, would it great to:

• add more options in windows installer to fill in prometheus/loki endpoints
• enable/disable logs collection

That way agent would be reporting data right after installation is done.

Is it possible to add an argument to the installer to configure extra arguments for the Windows service?
Currently need to add -config.expand-env.

It doesn't look like it's possible today, but we'd definitely accept a PR to add it.
