Master taints

[joaopedrocg27]

this will set NoSchedule right? Could we make it configurable to change to PreferNoSchedule ?

Variable k3s_master_taint will be used here (link) in all.yml

extra_server_args: >-
  {{ extra_args }}
  {{ '--node-taint node-role.kubernetes.io/master=true:NoSchedule' if k3s_master_taint else '' }}
  {% if calico_iface is defined or cilium_iface is defined %}
  --flannel-backend=none
  --disable-network-policy
  --cluster-cidr={{ cluster_cidr | default('10.52.0.0/16') }}
  {% endif %}
  --tls-san {{ apiserver_endpoint }}
  --disable servicelb
  --disable traefik

You can change extra_server_args variable having {{ '--node-taint node-role.kubernetes.io/master=true:PreferNoSchedule' if k3s_master_taint else '' }} instead.
