Current Kubespray supports the Kubernetes version 1.21 or upper with
`kube_version_min_required: v1.21.0`
Then kube_version v1.20- related code is not used at all.
This deletes those code for cleanup.
to remove deprecation warning:
> Flag --feature-gates has been deprecated, This parameter should be set via the config file specified by the Kubelet's --config flag.
* rename ansible groups to use _ instead of -
k8s-cluster -> k8s_cluster
k8s-node -> k8s_node
calico-rr -> calico_rr
no-floating -> no_floating
Note: kube-node,k8s-cluster groups in upgrade CI
need clean-up after v2.16 is tagged
* ensure old groups are mapped to the new ones
* Allow the eventRecordQPS setting to be set.
The eventRecordQPS parameter controls rate limiting for event recording. When zero, unlimited events can cause denial-of-service situations. For my situation, I don't need more than a setting of "5". This change allows me to configure the setting before creating the cluster.
* Allow the eventRecordQPS setting to be set.
The default settings (see types.go) is five. So, this change does not affect the cluster provisioning. However, it does allow for the setting to be changed.
