[loki-distributed] Gateway Ingress unable to skip TLS secret

[den-is]

Installation of loki-distributed with Gateway Ingress enabled is forcing you to use TLS secret for the host:

Chart values.yaml has default non-empty TLS secret defined:

helm-charts/charts/loki-distributed/values.yaml

Lines 939 to 942 in ccdb6f3

	tls:
	- secretName: loki-gateway-tls
	hosts:
	- gateway.loki.example.com

I'm deploying loki-distributed in an internal network where I do not need TLS/HTTPS communications with loki-gateway.

Passing null values during the helm install do not override not null default values.
I.e.: These do not work tls: [] or tls: null

This is a known bug helm/helm#5184

Please comment out the default value and keep them as an example.

At the same time the chart already has correctly disabled the default TLS secret for non-Gateway Ingress object

helm-charts/charts/loki-distributed/values.yaml

Lines 805 to 808 in ccdb6f3

	# tls:
	# - hosts:
	# - loki.example.com
	# secretName: loki-distributed-tls

Also because the ingress controller is seeing TLS secret configured for the Ingress object it automatically redirects traffic to HTTPS.
So I had to disable ssl-redirect:

        annotations:
          haproxy.org/ssl-redirect: "false"

This is a common config across many ingress controllers.
