Arthur Lenz b335387eac feat(k8s): Add basic support for Helm 3 in kubernetesDeploy step (#1438 )

* Extends kubernetesDeploy step to support Helm 3

Currently, the kubernetesDeploy step has no support to Helm 3 due to the fact that:
- the initialization command used works only for Helm 2
- the image used when running the helm CLI is based on Helm 2

The need for Helm 3 support comes from the fact that Helm 3 introduces major architectural changes,
more specifically, the removal of its server-side agent called Tiller - thus, being incompatible with
one another.

This commit adds this support by introducing a new configuration field (helmVersion).
By default, its values is set to 2 (Helm 2) to avoid breaking any existing functionalities.

* Use deployTool field to decide between Helm 2 or 3

* Remove helm init and replace wait for atomic in v3

* Update cmd/kubernetesDeploy.go

Nice catch!
