Section name [security_group] is wrong in sample config files

[Akihiro Motoki]

There are two duplicated configuration sections: security_group and securitygroup.
Reference dev ML thread: http://lists.openstack.org/pipermail/openstack-dev/2014-April/032086.html

[securitygroup] firewall_driver
[security_group] enable_security_group

We have [securitygroup] section exists in Havana and previous releases and it is the right section name.
When we introduced enable_security_group option, we seem to have added a new section
accidentally. We don't intended to introduce a new section name.

Both firewall_driver and enable_security_group are placed in [securitygroup].

It should be fixed before the release.

[Akihiro Motoki (amotoki)]

After I checked the code, it is a bug of sample configuration files only.
Sample config files should be updated.

[Akihiro Motoki (amotoki)]

Config files affected are:
- etc/neutron/plugins/bigswitch/restproxy.ini
- etc/neutron/plugins/ml2/ml2_conf.ini
