Windows commands for administrating ArangoDB

[Simran-B]

Pages about operating ArangoDB, such as upgrading starter deployments https://www.arangodb.com/docs/stable/upgrading-starter.html do not tell you that the commands are Linux-only (possibly macOS and Cygwin as well). As long as we support Windows as a platform, we should provide commands for that OS as well.

However, the following is not very nice to use:

 The output of the command above does not only show the PID's of all _arangodb_
 processes but also the used commands, which can be useful for the following
 restart of all _arangodb_ processes.

 When using a supervisor like _SystemD_, this will happen automatically. In case

We should use a widget with tabs that let's you pick the right OS and remember that choice. The commands obviously need testing, so this is a rather large undertaking.

Needs management decision whether we want to put any effort into non-Linux commands and terminals.
