3c8ad073cd Stop using kubeadm to update server in kubeconfigs (#7338)
Using `kubeadm init phase kubeconfig all` breaks kubelet client certificate rotation
as we are missing `kubeadm init phase kubelet-finalize all` to point to `kubelet-client-current.pem`

kubeconfig format is stable so let's just use lineinfile,
this will avoid other future breakage

This revert to the logic before 6fe2248314

fbdc2b3e20 Fix proxy usage when *_PROXY are present in environment (#7309)
Since a790935d02 all proxy users
should be properly configured

Now when you have *_PROXY vars in your environment it can leads to failure
if NO_PROXY is not correct, or to persistent configuration changes
as seen with kubeadm in 1c5391dda7

Instead of playing constant whack-a-bug, inject empty *_PROXY vars everywhere
at the play level, and override at the task level when needed

40857b9859 Ensure kubeadm doesn't use proxy (#7275)
* Move proxy_env to kubespray-defaults/defaults

There is no reasons to use set_facts here

Signed-off-by: Etienne Champetier <e.champetier@ateme.com>

* Ensure kubeadm doesn't use proxy

*_proxy variables might be present in the environment (/etc/environment, bash profile, ...)
When this is the case we end up with those proxy configuration in /etc/kubernetes/manifests/kube-*.yaml manifests

We cannot unset env variables, but kubeadm is nice enough to ignore empty vars

Allow the eventRecordQPS setting to be set. (#6880)
* 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.
