Description

Our function apps are returning an `ARRAffinity` response header. Per discussion by @paulbatum https://github.com/Azure/app-service-announcements/issues/74, this is unnecessary and unhelpful for function apps.

Quoting the announcement

> We are making two changes:
> * Fixing the bug that is turning Client Affinity on by default if the function app was not created through the portal.

This bug seems to have come unfixed.

## Repro

Create a function app with an ARM template that does not mention `clientAffinityEnabled`
* Function app has `clientAffinityEnabled = true`
* Function app returns ARRAffinity headers

(Function apps created through portal, do not have this issue. The ARM template which portal uses explicitly sets this setting to false)
