Contour v1.18.3

We are delighted to present version 1.18.3 of Contour, our layer 7 HTTP reverse proxy for Kubernetes clusters.

This is a backport release to 1.18, bringing the below change in.

Updates

Allow retry policy, num retries to be disabled

The field, NumRetries (e.g. count), in the RetryPolicy allows for a zero to be
specified, however Contour's internal logic would see that as "undefined"
and set it back to the Envoy default of 1. This would never allow the value of
zero to be set. Users can set the value to be -1 which will represent disabling
the retry count. If not specified or set to zero, then the Envoy default value
of 1 is used.
