This combines two commits in one
* Change aggregation method to mean
Commit 6061286c3133a4b85c4a72160960ecf6a82d02f8 handles
ignoring gnocchi api error when metric is not created.
However there are functional test failures when the
aggregation method is set to last for alarm type
gnocchi_aggregation_by_resources_threshold,
This fix changes the aggregration method to mean for
any create/update of alarm type
gnocchi_aggregation_by_resources_threshold.
* Update python testing as per zed cycle testing runtime
In Zed cycle, we have dropped the python 3.6/3.7[1] testing
and its support. Add release notes and update the python
classifier for the same.
