Units are appended to Y axis label on metrics dashboard
Recently units have started to be appended to the Y axis label on the metrics dashboard. This did not use to be the case, and can lead to some duplicate and odd text, like:
Latency (ms) (ms)
Requests / sec (req / sec)
We should either stop appending the unit text to the Y axis since our data format does not expect this, or update all of the Y labels to no longer include information on the unit type.
