glance/cinder/quantum counter units are not accurate/consistent

relating to: https://review.openstack.org/#/c/26115/3/doc/source/measurements.rst

in network counters pollster version of ip.floating* meters have 'ip' unit while notification version has 'floatingip' unit... not sure which is right but i would think one of them is wrong.

volume.size meter should be GB instead of B

image.[upload/update/delete] have unit value 'event'... 'image' might make more sense.
