Helm template add name and disable hook (#405)

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.
