Deprecated ansible features used during kubemaster and dashboard creation

[Loic-R]

There are some deprecated Ansible features used in kubernetes component. See trace bellow :

 [install] [KubernetesMaster] [create] [WARNING]: SELinux state temporarily changed from 'enforcing' to 'permissive'.
State change will take effect next reboot.
  [install] [KubernetesMaster] [create] [WARNING]: Consider using the yum module rather than running yum. If you need
to use command because yum is insufficient you can add warn=False to this
command task or set command_warnings=False in ansible.cfg to get rid of this
message.
[DEPRECATION WARNING]: Invoking "yum" only once while using a loop via 
squash_actions is deprecated. Instead of using a loop to supply multiple items 
and specifying `name: {{item}}-{{KUBERNETES_SELECTED_VERSION}}`, please use 
`name: [u'kubelet', u'kubeadm', u'kubectl']` and remove the loop. This feature 
will be removed in version 2.11. Deprecation warnings can be disabled by 
setting deprecation_warnings=False in ansible.cfg.
  [install] [KubernetesMaster] [configure] [WARNING]: Consider using the file module with state=link rather than running
ln. If you need to use command because file is insufficient you can add
warn=False to this command task or set command_warnings=False in ansible.cfg to
get rid of this message.
  [install] [KubernetesDashBoard] [create] [DEPRECATION WARNING]: Using tests as filters is deprecated. Instead of using 
`result|match` use `result is match`. This feature will be removed in version 
2.9. Deprecation warnings can be disabled by setting deprecation_warnings=False
in ansible.cfg.
