[Merge] lp:~paelzer/ubuntu-seeds/drop-ubuntu-virt-artful into lp:~ubuntu-core-dev/ubuntu-seeds/ubuntu.artful

It came up in the discussion that the argument against the meta package applies just as much to the task. That is absolutely true, so I modified the MP to remove all of the task as well.

But that might be more complex than we thought.
It seems that the virt-host definition at least is also used to pull in these parts into main?
At least there is:

cat STRUCTURE
[...]
server-ship: [...] virt-host

So we would like to drop the task, but not this dependency here.
[1] defined this as the union of server-ship and server-suppoerted, but there is no server-supported (atm).

There are examples for this as we want:
1. no task
2. still supported
3. do not mess the "ship" packages

E.g. "development" is having no Task and only used as definition file.
It is still referred as the other files - so for now assuming we can do so as well for virt-host.
That means we will:
1. drop the Task headers
2. keep it in server-ship as it is in STRUCTURE
