Improve apt_repository and supervisorctl

Add seboolean module

add selinux module

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.

Will manage values of seboolean on a host.  Options are name (name of
boolean), state (on or off), and persistent (on or off).  Persistent
defaults to no.

* 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.

The optional list is prepended to PATH.
Fix get_bin_path() to use os.path.join().

This is meant to assist all the modules that look for the full path of
an executable.  If it is found and is X_OK, returns the full path.
Otherwise, it returns None.
