Shall provide a way to register implicit conf options for generate_sample.sh

[xingzhou]

etc/ceilometer.conf.sample is generated by tools/conf/generate_sample.sh which will call ceilometer/openstack/common/config/generator.py. While generator.py will scan the ceilometer modules and write sample conf option enties if the module has global cfg.Opt attribute. But for some modules like storage, the conf option is located in corresponding engine class and will be registered when get_connection is called. This will prevent such conf options generated in ceilometer.conf.sample.

I would like to suggest we implement a new approach to let generator.py know what shall be written into the sample conf file.

It shall be simpler to always register storage options globally.
