Merge the toolbox role to the debian_server role.

The only reason it was a seperate role was because I thought it could be
useful for workstation. It is but it depends on a bunch of stuff from
the debian_server role. On a new host, it would fail to run before the
debian_server role has (it does because the debian_server role depended
on the toolbox role). When the need arises to use some of the
debian_server tasks in a workstation setting, it will need to be split
to a debian_common role.
