Helm template add name and disable hook
SUMMARY
This PR adds "disable_hook" and "name" (NAME of the release) as optional arguments to the helm_template module.
It contains the rest of my planned work towards #313.
ISSUE TYPE
Feature Pull Request
COMPONENT NAME
plugins/modules/helm_template.py
changelogs/fragments/313-helm-template-add-support-for-name-and-disablehook.yml
tests/unit/modules/test_helm_template.py
integration/targets/helm/tasks/tests_chart.yml
ADDITIONAL INFORMATION
The PR contains unit tests and an integration test for the new parameters added in this and the previous PR.
I limited the execution of the integration test to the local test chart, because the testing of the "show_only" parameter requires a known chart structure. As I think I do not have to test the workings of "helm template ..." itself, I hope this is sufficient.
Please adjust / comment as necessary.

ISSUE TYPE
Feature Pull Request #191
COMPONENT NAME
helm, helm_template
ADDITIONAL INFORMATION
There is a doc generated for history_max option for the helm module. I think that is not generated in the previous PR #164.
There is others changes affect the docs/ folder when I run the collection_prep_add_docs -p . command. These changes are added in the last commit 64eab40. I let you decide rather we keep the commit or remove it.
The --dependency-update insertion option is tested used a local helm chart repository create via docker. So here are the tasks that test this feature. Maybe if we create a GitHub repository for the helm chart, we can add this test code in the CI pipeline.

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.
ISSUE TYPE
Feature Pull Request
COMPONENT NAME
changelogs/fragments/313-helm-template-add-support-for-show-only-and-release-namespace.yml
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.
