[cetic/nifi] 0.6.1 Server with no auth skips setting custom nifi.properties

[jdesroch]

Describe the bug
nifi.properties values defined in .Values.properties.safetyValve are ignored unless .Values.auth.oidc.enabled

What happened:
0.6.1 adds the check {{- if .Values.auth.oidc.enabled }} on line 193 of templates/statefulset.yaml. This check means that custom nifi.properties values (line 215) are never set if .Values.auth.oidc is disabled.

What you expected to happen:

• Remove/refactor check for OIDC auth
• Modify nifi.properties using safetyValve values regardless of auth or other settings.

How to reproduce it (as minimally and precisely as possible):
Vanilla deploy of 0.6.1 with 2 replicas and no auth.
Add values to verify change

.Values.properties.safetyValve:
    nifi.ui.banner.text: 'Show this text'

Look for banner text in UI.
