Prometheus Operator - v0.66.0

After research, we noticed how the default CPU requests of the config-reloader container were too high compared to the effective usage. We decided to decrease the default CPU requests from 100m to 10m. For most environments, this won't make a difference but if you need to increase the values, you can use the -config-reloader-cpu-request and -config-reloader-cpu-limit CLI arguments of the Prometheus operator.
