Make topology implementation in helm configurable

[aberfeldy]

Feature Description

Currently etcd is hardcoded as topo-implementation in the helm chart Line 102
It would be nice to have that determined by a value from values.yaml, since zookeeper and consul are supported as well.

Use Case(s)

Users wouldn't have to rewrite/fork the helm chart in order to use a different topo-implementation on their Kubernetes cluster.

Thank you for the feature request.

@morgo Would like to work on this. Can this be assigned to me?

[morgo]

Be aware that there is also work in #5703 to add Kubernetes as a topo. I expect that after this is added, it will eventually become the default as it simplifies installs.
