This patch adds a var used by the repo_build process to determine
which host group to check for members of before building the pip
packages required by this role. This provides the ability to
optimise the repo build process to only building the packages
that are required for an environment.

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
