Comment 2 for bug 1544190

In Liberty and prior releases, the metadata_agent.ini file contained similar options [1] that became defunct by changes to the keystone middleware library. The file should contain the current variant of these options. After deprecation, I manually implemented the current variant of these options in the installation guide. However, the current metadata_agent.ini file generated by DevStack lacks these options, which tells me that the agent apparently reads them from elsewhere... perhaps the neutron.conf file. Not exactly sure when this changed, but I need to investigate further to determine the validity of this bug.
