The current method of installing the distribution packages required is
set in the tasks and cannot be changed by a deployer.
Currently the apt task always installs the latest package. This results
in unexpected binary changes when a deployer may simply be trying to
execute a configuration change.
This patch adds the ability for a deployer to change the desired state
so that the results are predictable.

Remove all tasks and variables related to toggling between installation
of rally inside or outside of a Python virtual environment.
Installing within a venv is now the only supported deployment.
Additionally, a few changes have been made to make the creation of the
venv more resistant to interruptions during a run of the role.
* unarchiving a pre-built venv will now also occur when the venv
directory is created, not only after being downloaded
* virtualenv-tools is run against both pre-built and non pre-built venvs
to account for interruptions during or prior to unarchiving

Debian-specific vars and logic have been moved to tasks
