As per victoria cycle testing runtime and community goal[1]
we need to migrate upstream CI/CD to Ubuntu Focal(20.04).
-Bump the lower constraints for required deps which added python3.8 support
in their later version.
-Changing the way to install and configure Zookeeper.
Installing Zookeeper from official Apache's tarball.
Adding the possiblity to set the specific Zookeeper version.
Minor change in zookeeper logger.
-Use mariadb JDBC for monasca-thresh in devstack, since Drizzle isn't
compatible with MySql Server v8.0.x which is default in Focal
-Python 3.8 doesn't seem to like dictionary keys changing during
iteration.
Fixing RuntimeError: dictionary keys changed during iteration.
Tech. details:
It runs well in py27: 5 iterations
It runs risky in py37: 7 iterations
It is forbbiden in py38: raised RuntimeError
Fixed with list(dic.items()) or tuple(dic.items())
dic = {'1': 'a', '2': 'b', '3': 'c', '4': 'd', '5': 'e'}
for key, value in dic.items():
print("Key: {0} Value: {1}".format(key,value))
del dic[key]
print(dic)
dic[key] = value
print(dic)
