Description
This PR enabled setting a custom
schedulerNameto be used by AlertManager/Prometheus/PrometheusAgent pods.This is needed because in AWS EKS it's not possible to do any configuration changes in the
default-schedulerprovided by EKS. Therefore users of EKS which are in need of configuring the scheduler, are forced to use a scheduler with a different name, which in turn means they need to configure that scheduler name on all workloads including prometheus.This is related to: #4691
