On a reasonably sized cluster:
63 nodes
87 services
90 endpoints
The initialization of the k8s provider would hang.
I tracked this down to the ResourceEventHandlerFuncs. Once you reach the
channel buffer size (10) the k8s Informer gets stuck. You can't read or
write messages to the channel anymore. I think this is probably a lock
issue somewhere in k8s but the more reasonable solution for the traefik
usecase is to just drop events when the queue is full since we only use
the events for signalling, not their content, thus dropping an event
doesn't matter.
Add compatibility with labels: `HAPROXY_GROUP` and `HAPROXY_0_VHOST`.
* `HAPROXY_GROUP` become a new tag
* `HAPROXY_0_VHOST` become a rule `Host:`

- React to health_status events
- Filter container that have a health status *and* that are not healthy

This change adds sticky session support, by using the new
oxy/rr/StickySession feature.
To use it, set traefik.backend.sticky to true.
This is currently only implemented in the wrr load balancer, and against
the Marathon backend, but lifting it should be very doable.
In the wrr load balancer, a cookie called _TRAEFIK_SERVERNAME will be
set with the backend to use. If the cookie is altered to an invalid
backend server, or the server is removed from the load balancer, the
next server will be used instead.
Otherwise, the cookie will be checked in Oxy's rr on access and if valid
the connection will be wired through to it.
Initial implementation: Force both to be present to trigger behavior.
add ability to see rendered template in debug
add support for loadbalancer and circuit breaker specification
add documentation for new configuration
Healthcheck are not mandatory, so if a result is not present, assume it
is ok to continue. Fixes the case when a new leader is elected and
don't have any healthcheck result's, returning 404 to all requests.

We added the ability to filter the ingresses used by traefik based
on a label selector, but we shouldn't need to have matching
labels on every other resource, Ingress allready has a way
to explicty choose which pods end up in the load ballancer
(by refering to the membership of a particular service)
The TargetRef contains information from the object referenced
by the pod, unless the service has been set up with bare
endpoints - i.e. not pointing at pods this information
will be present.
It just makes the information that we show in the web-ui
a little more constent with that shown in kubectl
and the kuberntes dashboard.
… making it possible to use in other packages ; and thus in the
User-Agent header for the docker client.
Also removing the dockerverion hack as it's not required anymore.
