By default, Nginx does proxy buffering and it may store big replies to a
temporary file up to 1 GB. It also means that Nginx will read data as
fast as possible from Garage, even if the client downloads slowly. Both
behaviours are often not wanted, so disable this temporary file in the example.
Ref: https://nginx.org/en/docs/http/ngx_http_proxy_module.html#proxy_buffering
Also add an example of upstream with a "backup" server, which may be
useful to only use remote servers as fallback.

This commit adds support to discover garage instances running in
kubernetes.
Once enabled by setting `kubernetes_namespace` and
`kubernetes_service_name` garage will create a Custom Resources
`garagenodes.deuxfleurs.fr` with nodes public key as the resource name.
and IP and Port information as spec in the namespace configured by
`kubernetes_namespace`.
For discovering nodes the resources are filtered with the optionally set
`kubernetes_service_name` which sets a label
`garage.deuxfleurs.fr/service` on the resources.
This allows to separate multiple garage deployments in a single
namespace.
the `kubernetes_skip_crd` variable allows to disable the creation of the
CRD by garage itself. The user must deploy this manually.
Fixes#234, among other things
