This change removes restrictions to allow adding exemplars to all time series. It also contains some improvements in test values so that it is easier to track what is tested. The advantage of doing this is having a little less error-prone tests: "yy" is not really descriptive but "counter-test" can give people a better idea about what is tested so it is harder to make mistakes.
