Description of problem:

If there is typo or misspelled configuration value in configuration files - restarting of service will not fail - even there is parameter in configuration file which is obviously wrong 


Version-Release number of selected component (if applicable):

my test was with below packages 

atomic-openshift-clients-3.2.0.44-1.git.0.a4463d9.el7.x86_64
atomic-openshift-master-3.2.0.44-1.git.0.a4463d9.el7.x86_64
tuned-profiles-atomic-openshift-node-3.2.0.44-1.git.0.a4463d9.el7.x86_64
atomic-openshift-node-3.2.0.44-1.git.0.a4463d9.el7.x86_64
atomic-openshift-sdn-ovs-3.2.0.44-1.git.0.a4463d9.el7.x86_64
atomic-openshift-3.2.0.44-1.git.0.a4463d9.el7.x86_64


How reproducible:

Here is example of my test

- configure metrics following https://github.com/openshift/origin-metrics
- misspell metricsPublicURL and write it as metricsPublicUrl

- restart openshift master service - which will be successful 

- it is expected to see metrics tab in openshift interface - but it will not be there due to wrong parameter name in master configuration file 

Steps to Reproduce:
see above 

Actual results:

- systemctl restart atomic-openshift-master 
will work without error - thought there is wrong parameter in configuration file 

- metrics tab will not be visible in openshift web interface 

Expected results:

systemctl restart atomic-openshift-master 

to fail ( and eventually point out where bad line is )
