Set container create tasks to non-voting/fix pkg

There are some inter-dependencies here where the container tasks will
not pass until a few updates are in both here and elsewhere. This change
sets the container create tasks to non-voting until all of the required
updates get in.

Remove the aria2 requirement

While aria2 has some nice features, the get_url command can do most of
what we need and does so in a far more universal way. This change
removes the aria2 dependency and updates the aria2 tasks to use the
get_url module.
