Subject: [PATCH] Define a standard commandline for applying manifests
This is expected to be used in the command module this way:
command:
cmd: "{{ kubectl_apply_stdin }}"
stdin: <... rendered manifests > -> using the 'template' lookup plugin
in most cases.
The advantages over the kube plugin module integrated in kubespray
(which this should replace eventually):
- way easier to modify to take advantage of new features (server-side
apply for instance)
- no need for a separate template tasks + checking the result (which can
introduce problem if the first playbook runs encounters an error).
