* fix switch order
* remove fallthough
* add test
* fix test
* distingush nxdomain/nodata for at least first subdomain of zone
* restore fallthough; reorder switch cases
Various fixes to make things less flaky:
* kubernetes: put klog.SetOutput in the setup function, not in the init
function to see if that helps
* file: make z.Expired a boolean instead of a pointer to a boolean
* test: fix TestSecondaryZoneTransfer test, which wasn't actually
testing in the right way. It's more right now, but may still be racy
(race introduced because a file's lazy loading of zones)

I don't believe this is actually needed (anymore). The:
os.Stderr = os.Stdout
is a crazy hack that def. needs to go.

Don't add pods to our internal cache that are being deleted. This saves
a field in the struct as well.
Add (extra) comments about adding fields to the
object/{Pod,Service,Endpoint} structs.

* Fix for #2842, instead of returning the first Pod, return the one which is Running
* a more memory efficient version of the fix, string -> bool
* fix with no extra fields in struct, return nil at Pod conversion if Pod is not Running
* let Kuberneretes filter for Running Pods using FieldSelector
* filter for Pods that are Running and Pending (implicit)
* kubernetes: never respond with NXDOMAIN for authority label
Return a nodata response when trying to resolve the authority's label
for a record type that doesn't match the record type of the authority.
This guards against poisoning the authority record by requesting the
wrong record type for the authority label. For instance, given an
authoritative resolver that uses subdomain delegation for Kubernetes
services of a cluster that's configured to use IPv4, the parent may be
poisoned by querying it for the authority label of the cluster subdomain
with a AAAA record type, which would otherwise (i.e. without this
change) return an NXDOMAIN. That is, given
cluster.example.com NS 10800 ns.dns.cluster.example.com
ns.dns.cluster.example.com A 10800 10.0.1.2
The parent may be poisoned for the SOA TTL by querying it for a AAAA
record of ns.dns.cluster.example.com, causing the parent to fail
delegate properly until the SOA TTL lapses.
* kubernetes: add tests for authority queries
Various plugins still had this documented, the setup functions still
allow it (which is fine), but update the docs that this arguments isn't
there any more.

* Remove context.Context from request.Request
This removes the context from request.Request and makes all the changes
in the code to make it compile again. It's all mechanical. It did
unearth some weirdness in that the context was kept in handler structs
which may cause havoc with concurrently handling of requests.

* plugin/health: remove ability to poll other plugins
This mechanism defeats the purpose any plugin (mostly) caching can still
be alive, we can probably forward queries still. Don't poll plugins,
just tell the world we're up and running.
It was only actually used in kubernetes; and there specifically would
mean any network hiccup would NACK the entire server health.
