According to the document[1], audit-webhook-batch-max-size and
audit-webhook-batch-max-wait are used only in the batch mode.
This adds a condition to avoid unnecessary writting on the config.

This PR is to move the cilium kvstore options to the configmap
rather than specifying them in the deployment as args. This
is not technically necessary but keeping all the options in
one place is probably not a bad idea.

Tested with cilium 1.9.5.

When attempting a fresh install without cilium_ipsec_enabled I ran
into the following error:

failed: [k8m01] (item={'name': 'cilium', 'file': 'cilium-secret.yml', 'type': 'secret', 'when': 'cilium_ipsec_enabled'}) =>
{"ansible_loop_var": "item", "changed": false, "item": {"file": "cilium-secret.yml", "name": "cilium", "type": "secret",
"when": "cilium_ipsec_enabled"},"msg": "AnsibleUndefinedVariable: 'cilium_ipsec_key' is undefined"}

Moving the when condition from the item level to the task level solved
the issue.

* Add KubeSchedulerConfiguration for k8s 1.19 and up

With release of version 1.19.0 of kubernetes KubeSchedulerConfiguration
was graduated to beta. It allows to extend different stages of
scheduling with profiles. Such effect is achieved by using plugins and
extensions.

This patch adds KubeSchedulerConfiguration for versions 1.19 and later.
Configuration is set to k8s defaults or to kubespray vars. Moving those
defaults to new vars will be done in following patch.
