[bitnami/contour] Add the possibility to set HostIP (#6000)

* [bitnami/contour] Add the possibility to set HostIP

The cart does not allow setting the `hostIP` parameter on the
Envoy Deamonset. This is useful in certain cases (e.g. with `k3s`
and single-node deployments) and should be possible.

This commit simply adds the possibility to set the `hostIP` on ports
exposed by Envoy.
