Added apt update tasks to everything using apt
Added apt update tasks to everything using apt

This change adds a specific update task to all tasks that all the
apt ansible module. This change was done to ensure that the cache
is updated as expected when instructed to do so. The reason that
the cache update is being removed from the grouping is because
there is an upstream bug that is effecting the process by which
the apt cache is updated when there is a package list to process
within the same task. The work around to make this function as
expected is to move the update into its own task without a package
list.
