helm_template: add optional show_only and release_namespace arguments
SUMMARY
This PR adds the "show_only" and "release_namespace" as optional arguments to the helm_template module.
It does some work towards #313.

plugins/modules/helm_template.py
tests/unit/modules/test_helm_template.py
ADDITIONAL INFORMATION
The PR does include unit tests instead of integration test.
Reasoning:
The existing integration tests already include a task based on helm_template. So we know that the module does a proper job of using the command line generated inside the module to call helm.
As I trust helm itself to "do its job" correctly, all that should be necessary is to test the correct generation of the command line itself. The included unit tests hopefully do a proper job.
With regards of the pretty long testing times for the module, I really prefer unit tests, if at all possible.
Please let me know if this fits.

helm_template: change order of values_release and values_files
SUMMARY
This fix aligns precedence of release_values and values_files in kubernetes.core.helm_template with the one in kubernetes.core.helm.
The values in release_values are now processed last, thus with the highest precedence.
This allows overwriting of values in values_files with the values presented in release_values.
