2e9986c622 Add alternate option to forward plugin (#6681) 
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

6706ee8419 Return RcodeServerFailure when DNS64 has no next plugin (#6590) 
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.

0d6e113f90 Enable Prometheus native histograms (#6524) 
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.

b541b4ea49 Use the correct root domain name in the proxy plugin's TestHealthX tests (#6395) 
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.

52f0348312 Change default value to 1232 (#6183) 
* 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.
