**What**
- Removes the `alert` label in the scale-up alert
- Updates the annotaitons to use the `function_name` label instead of
the `instance` label that was removed.
- Per prometheus/prometheus#4836 and the related mailing list discussion
https://groups.google.com/d/msg/prometheus-users/7Ul6ngc7Ogs/j_YDszV5BwAJ


the alert value should not be included in the alert labels otherwise
each calculation of the alert is treated like a new alert and then the
use of `for 5s` will not behave as expected.
- Ports the resoltuion openfaas/faas-netes#372
