Rudder

So, after testing and discussing with our local Scala experts, I see that executing the command to reload the server during policy generation is done "execve" style in Scala, meaning it takes ONE command and its arguments,

The best approach I can come with for this is to just delegate all the magic to a dedicated script, for several reasons:

• No more fiddling with process execution magic
• One script to do it, and do it well instead of an unreadable line in the .properties (we've done this before in cron, never again...)

Therefore, I'm adding subtickets to:

• Change in rudder the command to be executed in the sample properties(and correct a small but horribly frustrating logging typo)
• Adapt the packaging to add the right line during migration, and package the script itself
