Optimize getting unit in "metering" dashboard

Currently we using a meter-list for getting a "unit" for metric.
Meter list get all available metric on environment,
it's may be a thousands of records.
It's better to use sample-list for this metric with "limit" 1,
for geting "unit" from a 1 sample with queried metric.
