Ingress should point to the "not headless" service

[colearendt]

Describe the bug
The couchdb chart generates two services. The ingress generated by the chart points at the headless service, which is suspected to be a bug since the headless service is defined for the purposes of statefulset maintenance. The client service's niceties (i.e. setting annotations) cannot be used as expected because of this bug.

Tangentially related to #69 , since ingress class can also be set by service annotations in some cases

Version of Helm and Kubernetes: N/A

What happened:

Cannot set annotations on the ingress's service

What you expected to happen:

Set annotations on the ingress's service

How to reproduce it (as minimally and precisely as possible):

couchdb-helm/couchdb/templates/ingress.yaml

Line 2 in 78eff8c

{{- $serviceName := include "couchdb.fullname" . -}}

couchdb-helm/couchdb/templates/headless.yaml

Line 4 in 78eff8c

name: {{ template "couchdb.fullname" . }}

couchdb-helm/couchdb/templates/service.yaml

Line 5 in 78eff8c

name: {{ template "couchdb.svcname" . }}
