i'm attempting to add support for the cinder capacity notifications that 
were added a while back[1].

adding measurement support in ceilometer is pretty simple where in most 
cases you just add an entry to a yaml file[2]. the problem i have right 
now is i have no idea what resource these measurement are measuring so 
i'm unsure how to name the measurement in ceilometer so a user can 
understand what it's measuring.

the following are probably stupid questions but i see it measures two 
different resource types, a 'pool' and a 'backend' and they are 
ultimately tied to a host. are these measuring the amount of disk on 
each host? our pools confined to a host?

anyone with better knowledge is welcomed to take over my patch.
