* Set SOA record TTL as min of TTL/MINIMUM
According to
https://tools.ietf.org/html/rfc2308#section-3:
The TTL of this record is set from the minimum
of the MINIMUM field of the SOA record and the
TTL of the SOA itself, and indicates how long a
resolver may cache the negative answer.
Set the TTL accordingly so as to not always
negative cache SOA records for 300 seconds.
* Inline min func
* Update SOA record tests
* Fix types
* 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.

* 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.
