Bug 1687397

Description of problem:
In tuned 2.10, the "tuned-adm recommend" command used to work when the tuned daemon was stopped.  In tuned 2.11 rc1, it does not.

Version-Release number of selected component (if applicable):
tuned-2.11.0-0.1.rc1

How reproducible:
Always.


Steps to Reproduce:
1. Remove old tuned package
2. rpm -ivh tuned-2.11.0-0.1.rc1.el7.noarch.rpm
3. make sure the tuned daemon is stopped
4. tuned-adm recommend

Actual results:
root@b1: /var/lib # systemctl stop tuned
root@b1: /var/lib # rpm -qi tuned

Summary     : A dynamic adaptive system tuning daemon
Description :
The tuned package contains a daemon that tunes system settings dynamically.
It does so by monitoring the usage of several system components periodically.
Based on that information components will then be put into lower or higher
power saving modes to adapt to the current usage. Currently only ethernet
network and ATA harddisk devices are implemented.
root@b1: /var/lib # tuned-adm recommend
Cannot talk to Tuned daemon via DBus. Is Tuned daemon running?
Traceback (most recent call last):
  File "/usr/sbin/tuned-adm", line 119, in <module>
    result = admin.action(action_name, **options)
  File "/usr/lib/python2.7/site-packages/tuned/admin/admin.py", line 89, in action
    res = action(*args, **kwargs)
  File "/usr/lib/python2.7/site-packages/tuned/admin/admin.py", line 315, in _action_recommend_profile
    print(self._cmd.recommend_profile())
AttributeError: commands instance has no attribute 'recommend_profile'


Expected results:
Warning that the Daemon is not running is acceptable, but tuned-adm should return the recommended profile.

Additional info:
This bug would break the functionality in containerized tuned shipping in OCP 4.0

Run with old tuned:
root@b2: ~ # systemctl stop tuned
root@b2: ~ # rpm -qi tuned
