Add the ability to customize the kube-controller-manager and kube-scheduler arguments

[drustan]

Description

I recently installed the kube-prometheus-stack on my RKE2 cluster and I had to modify the bind address for both kube-controller-manager and kube-scheduler. This enable the ability to do so.

Type of change

• arguments customization of kube-controller-manager
• arguments customization of kube-manager

How Has This Been Tested?

Tested on my cluster :

LGTM

@MonolithProjects, IMO it is better to config rke2_server_options without creating new variable

rke2_server_options:
  - "kube-controller-manager-arg: ['bind-address=0.0.0.0']"

Hi @hoangphuocbk

If it seems like a good idea for the sake of simplicity, defining rke2_server_options at the host level (in host_vars), such as for specifying the node-ip parameter, would take precedence over rke2_server_options at the group level. In that case, following your suggestion would require defining cluster-wide options in the host_vars file of every host.

I hope that what I'm trying to say is clear and understandable ^^
