This adds two dependencies to the apt_repository module: apt and
apt_pkg. These come from the package python-apt. This is used to parse
the host's sources.list and examine whether the repo is already
configured. This then eliminates the unnecessary
'add-apt-repository --remove' from running.
This updates apt, apt_repository, command, cron, easy_install, facter,
fireball, git, group, mount, ohai, pip, service, setup, subversion,
supervisorctl, svr4pkg, user, and yum to take advantage of run_command
in module_common.py.
Added required as optional argument to get_bin_path(). It defaults to
false. Updated following modules to use required=True when calling
get_bin_path(): apt_repository, easy_install, group, pip,
supervisorctl, and user.
Also removed _find_supervisorctl() from supervisorctl module and updated
_is_running() to not need it.
* Migraed easy_install, pip, service, setup, and user.
* Updated fail_json message in apt_repository
* Fixed easy_install to not hardcode location of virtualenv in
/usr/local/bin/.
* Made handling of virtualenv more consistent between easy_install and
pip.
