[prometheus-redis-exporter] multipleTarget issue

[emily-ganze]

Describe the bug a clear and concise description of what the bug is.

Hello,

When enabling multipleTarget, the REDIS_ADDR env variable is still defaulted to values.redisAddress and mutlipleTarget is not considered in the deployment template.

deployment template:

          env:
            - name: REDIS_ADDR
            {{- if .Values.redisAddressConfig.enabled }}
              valueFrom:
              {{- if .Values.redisAddressConfig.isSecret }}
                secretKeyRef:
              {{- else }}
                configMapKeyRef:
              {{- end }}
                  name: {{ .Values.redisAddressConfig.source.name }}
                  key: {{ .Values.redisAddressConfig.source.key }}
            {{- else }}
              value: {{ .Values.redisAddress }}
            {{- end }}
