defaulting to localhost makes things explicit in CoreDNS code, and will give us valid URIs in
the logs

* Drop obsolete client-go auth plugins
The OpenStack plugin is no longer available, even in version 0.24.4 of
client-go; see
https://github.com/kubernetes/client-go/blob/v0.24.4/plugin/pkg/client/auth/openstack/openstack_stub.go
It is replaced by the client-keystone-auth credential plugin. The
plugin has been entirely removed in client-go 0.26.0, which breaks the
build when any other dependency pulls in client-go 0.26.0 or later.
The GCP plugin is deprecated in K8s 1.22+ and unavailable in 1.26+
(although it is still stubbed in client-go 0.26.0). Is it replaced by
the gke-gcloud-auth-plugin credential plugin.

* plugin/edns: remove truncating of question section on bad EDNS version
EDNS requests of "Unknown Version" removed the query section altogether.
Not sure why since this is not require (see [link](https://kb.isc.org/docs/edns-compatibility-dig-queries)
This cause issues with DNS solutions that uses this information (initial queried name, type and class) in order to route the response to the right client (e.g. PDNS).
The change here is to keep the inital query section as is.

Both block and filter actions write responses to the client based upon
the source IP address of the UDP packet containing the query. An
attacker spoofing the source IP address to that of their target, can
elicit a response to be sent to the victim host, known as DNS
Reflection. If an attacker is able to elicit a large response from a
relatively small query, with a spoofed source IP address, they are able
to increase the amount of data sent to the victim, known as DNS
Amplification. Scaling this from one to many queries allows an attacker
to perform an effective Denial of Service (DoS) attack against their
target.
Adding the drop action enables CoreDNS to ignore queries of a given
type or network range from being processed and a response written,
where an operator knows ahead of time, should not originate or be
destined to.

* introduce new interface "dnsserver.Viewer", that allows a plugin implementing it to decide if a query should be routed into its server block.
* add new plugin "view", that uses the new interface to enable a user to define expression based conditions that must be met for a query to be routed to its server block.
