Allow overriding the metadata.name field in Helm chart for Deployment

[bderrly]

I am using a custom Helm chart which includes this humio-operator Helm chart as a dependency. The Deployment name here is an unfortunate choice as the term humio is used all over the place including both the name of the chart I am using and possibly the Helm release name.

I would like to see the option to override the name of the Deployment (or even hard code it to humio-operator though this is not as flexible and will cause churn for already deployed installations).

This came about as a result of running the humio-operator in the same kubernetes namespace where the HumioCluster was configured to run as well. The HumioCluster CR is part of an internal Helm chart. The name of the release was humio which caused naming conflicts with the resources applied by the operator. I am going to run the operator in a separate namespace which should keep this from being an issue for me going forward but it is still something that should be considered to be a good citizen in the ecosystem. In my (albeit limited thus far) experience with Helm charts many groups allow overriding the name.
