Enable RFC7230_LEGACY http compliance on application connectors by default

Problem

When using the helm chart in the past, this config wasn't set by default, causing a basic install of the chart to fail and the issue fixed in #1419 to regress.

Solution

Add this value to the helm chart configmap by default
