"... has label dimensions inconsistency with previously collected metrics in the same metric family" error

Hi,

it seems that in some cases stackdriver-exporter got some errors when building prometheus metrics from stackdriver ones. On one of our projects we get the following output from the /metrics endpoint:

curl http://localhost:9255/metrics
An error has occurred during metrics collection:

6 error(s) occurred:
