Use appVersion as default tag for Pulsar images (#200)
Co-authored-by: Michael Marshall <mmarshall@apache.org>

### Motivation

There was a suggestion [in a dev mailing list discussion](https://lists.apache.org/thread/bgkvcyt1qq6h67p2k8xwp89xlncbqn3d) that the Helm chart's appVersion should be used as the default image tag.

### Additional context

There are some limitations in Helm. It is not possible to set "appVersion" from the command line. There's in an open feature request https://github.com/helm/helm/issues/8194 to add such a feature to Helm.

### Modifications

- change default values.yaml and set the tags for the images that use the Pulsar image to an empty value
- add "defaultPulsarImageTag" to values.yaml
- add a helper template "pulsar.imageFullName" that contains the logic to fall back to .Values.defaultPulsarImageTag and if it's not set, falling back to .Chart.AppVersion
- use the helper template in all other templates that require the logic
