* Upgrade antonmedv/expr to expr-lang/expr
The project has moved. This also upgrades from 1.15.5 to 1.16.9.
The expr project lacks a changelog but tests pass and the changes don't
seem to change it much - but there were a lot of changes.

Allows the forward plugin to execute the next plugin based on the return code. Similar to the externally mainted alternate plugin https://github.com/coredns/alternate
Based on the idea of chrisohaver@ in #6549 (comment)
Also incoperated the request to rename `alternate` to `next` as an option
I am having issues adding a proper test for functionality. Primarily, I do not know the code base enough and having multiple `dnstest.NewServer` with ResponseWriter does not work. From my testing these are "Singletons'' and only the last defined response writer is used for all servers

If using a coredns config with only the dns64 plugin specified, the
`Next` plugin that dns64 will attempt to call will be nil, resulting in
a nil pointer dereference. We should return an error instead of
crashing.

Add a NativeHistogramBucketFactor parameter to the use of
`NewHistogramVec` in order to enable use of Prometheus Native
Histograms.
This will store automatically computed sparse buckets in CoreDNS.
If a compatible Prometeus requests native histograms this data will
returned instead of the static buckets.
The default factor of 1.05 should provide high quality resolution data.

* plugin/cache: key cache on Checking Disabled (CD) bit
Key the cache on CD bit, which effectively separates the entries for
queries with CD disabled or enabled.

When packing the empty domain name, miekg/dns can end up creating
corrupt DNS messages. With some planned unpacking changes, this now
trips an error condition and causes these tests to fail. Correct this
by using the root domain explicitly as this gets correctly encoded on
the wire.

* Change default value to 1232
As specified by DNS flag day 2020, good and decent default value
avoiding fragmentation issues should be 1232. It is quite likely 1500
would work reliably on local ethernet networks.
Value 512 is set implicitly and must be used for all clients, which did
not include OPT RR with explicit value they support.
Since MR #5368 it should work correctly.
