* Convert to runtime.Object to smaller structs
This adds conversion for all the objects we want to keep in the cache.
It keeps the minimum for CoreDNS to function and throws away the rest.
The conversion:
api.Endpoints -> object.Endpoints
api.Pod -> object.Pod
api.Serivce -> object.Service
We needed to copy some client-go stuff to insert a conversion function
into NewIndexInformers.
Some unrelated cleanups in the watch functionality as that needed to be
touched because of the above translation of objects.

* re-introduce append here
We can't really use len() here because we don't know the number before
hand.

* Set incoming object to nil
Explicataliy discard the converted object; we did a deep copy it's
not needed anymore.

Hook up dynamic SOA serial by setting ResourceEventHandlerFuncs in
dnsController.
Add prototype of returns msg.Services via the Transfer function. Leave
expanding this to RRs out of scope for a bit.
* plugin/kubernetes: axfr
Respond to AXFR queries
* Fixing race condition
* Fixing instantiation of dnstest writer
* Updates from review
* Update k8s client-go to v6.0.0
This fix updates k8s client-go to v6.0.0 as CoreDNS is supported
in 1.9 and v6.0.0 is the recommended version.
There are quite some massive changes that need to be made:
1. k8s.io/client-go/pkg/api/v1 has been changed to k8s.io/api/v1 (repo changed from `client-go` to `api`)
2. kubernetes.Clientset adds one extra layer, so that `kubernetes.Clientset.Services()` and like has been changed to `kubernetes.Clientset.CoreV1().Services()`
Also, we have to stick with specific commits of `k8s.io/apimachinery` and the newly introduced `k8s.io/api`
because go dep still could not figure out the right version to fetch.

* plugin/kubernetes: Add GetNamespaceByName
A bare or wildcard query for just the namespace should return NODATA,
not NXDOMAIN, otherwise we deny the entirety of the names under the
namespace.
Add test to check for this in pod verified mode.
* Review
More comments and move namespace code to namespace.go
* plugin/kubernetes: wait until api is ready
Wait for HasSynced before allowing startup to avoid startup race.
Also do a small refactor in findServices() to pull a check out of the
loop - only needs to be done once.
* sigh
* Rename middleware to plugin
first pass; mostly used 'sed', few spots where I manually changed
text.
This still builds a coredns binary.
* fmt error
* Rename AddMiddleware to AddPlugin
* Readd AddMiddleware to remain backwards compat
