conf file with spaces before data cause error

[Roey Dekel]

Add a space before a conf line cause failure at restarting the service.
example via nova.conf:

rabbit_hosts=10.35.186.132:5672
                ==>
 rabbit_hosts=10.35.186.132:5672

cause:
[root@controller ~(keystone_admin)]# openstack-service restart

Hi, Adding space before a conf line is causing same error in all other components also(Tried with neutron.conf, glance.conf ). As of my understanding fix is required in oslo_config/iniparser.py file. This change will effect for all other components. Please suggest.

Working as designed. it's reporting that you have a problem with the ini file...no?
