Address k8s plugin code smells reported by sonar

Make 'resources' argument to k8sclient.k8sclient.deploy an
optional kwarg, update its uses and document it.
Split off code reported complex from deploy into functions.
Tweak a nested if in tasks.

+## [1.7.2]
+* DCAEGEN2-2006 Reduce code complexity
+ The k8sclient.k8sclient.deploy function parameter 'resources' is now an optional
+ keyword argument, i.e. it must be passed named and not as a positional argument.
+
 ## [1.7.1]
 * DCAEGEN2-1988 Customize python import for kubernetes plugin
