mongos: add RuntimeDirectory to systemd unit file

[schlitzered]

This adds RuntimeDirectory and RuntimeDirectoryMode to the mongos systemd unit file template to ensure /run/mongodb is created with the correct permissions.

Also fixes a bug in the mongos service manifest where service_group was incorrectly passed as service_user to the unit file template.

as said above, please rebase. a merge isn't a rebase :)

From your working directory, you can rebase and squash with:

git fetch origin            # Download the latest code we have here
git rebase -i origin/master # Interactively rewrite history moving your commits on top of the main branch

This will bring your editor listing all commits in your branch. Keep the first line unchanged, and replace pick with squash for all subsequent lines. Save and quit, your editor will pop again and allow you to combine all the commit messages in a single one.

Then push your updated branch:

git push -f            # Send the changes (-f is required because we re-wrote history)

not sure if i did the right thing now... but now there is only one commit, and i do not see any conflicts.

if not, please try to explain in detail what you expect, with the assumption in mind that i am a 3 year old that likes to eat clay ;)
