Verbatim copy of the current set of notes on coredns.io. Copy them
here to make them authoritative.
'make sync' on the coredns.io site copies them back in. They need to be

* Fixing panic in case if there's no response
There could be a situation when there's no response after ServeDNS call. With the current implementation, this leads to panic.

Part of the changes in 2591 modifies the vendor directory
which should not be modified. `dep ensure` will change it back.
This fix reverts the change of
```
vendor/github.com/apache/thrift/lib/go/thrift/simple_json_protocol.go
```
in 2591.

Currently, there are some links that we access with **HTTP**, it is
redirected to **HTTPS** automatically. So this commit aims to
replace **http://...** by **https://...** for security.

Reload didn't take proper care to protect the fields from use in
different goroutines. Add a mutex and add helpers for usage and
interval.

TestLookupAutoPathErratic sometimes fail on TravisCI saying below
```
=== RUN TestLookupAutoPathErratic
--- FAIL: TestLookupAutoPathErratic (8.30s)
erratic_autopath_test.go:39: Test 0, failed to sent query: "read udp [::1]:39758->[::1]:56643: i/o timeout"
FAIL
```
The failure happens when Google replies slowly.
This PR changes to not use Google but run CoreDNS locally and proxy to the server.
---
Because the failure depends on Google, sometimes it happens frequently but sometimes it doesn't happen.
I hope following test help you reproduce it.
```
func TestLookupAutoPathErratic2(t *testing.T) {
for i := 0; i < 200; i++ {
TestLookupAutoPathErratic(t)
}
}
```
or I can reproduce it by changing proxy to other DNS like 1.1.1.1 instead of 8.8.8.8 too
* Fix some typos
Corect some words for reading more easily
* Update NOERROR response code
NOERROR is a response code so I revert the typo checking for it
The [ADDRESS] field in the metrics plugin is not explained in a manner
that makes it immediately obvious, that what we are talking about here
is a listening address.
* plugin/hosts provide more configuration flexibility
This patch adds few features to the host plugin
* no-reverse (both as first argument on the plugin line and inline)
disable the automatic generation of reserve entries for hosts
* ttl <duration> (inline only atm)
allows to change the default ttl (default 5 minutes)
* reload <duration> (inline only atm)
allows to change the reloading interval (default 5s)
* plugin/hosts remove superfluous parameters to parse
* pkg/replace: make it more efficient.
Remove the map that is allocated on every write and make it more static,
but just defining a function that gets called for a label and returns
its value.
Remove the interface definition and just implement what is needed in our
case. Add benchmark test for replace as well.
Extend metadata test to test multiple values (pretty sure this didn't
work, but there wasn't a test for it, so can't be sure).
Update all callers to use it - concurrent use should be fine as we pass
everything by value.
Benchmarks in replacer:

old: BenchmarkReplacer-4 300000 4368 ns/op 384 B/op 11 allocs/op
Added benchmark function to the old code to test it.
~~~
func BenchmarkReplacer(b *testing.B) {
w := dnstest.NewRecorder(&test.ResponseWriter{})
r := new(dns.Msg)
r.SetQuestion("example.org.", dns.TypeHINFO)
r.MsgHdr.AuthenticatedData = true
b.ResetTimer()
b.ReportAllocs()
repl := New(context.TODO(), r, w, "")
for i := 0; i < b.N; i++ {
repl.Replace("{type} {name} {size}")
}
}
~~~
New code contains (of course a different one). The amount of ops is
more, which might be good to look at some more. For all the allocations
is seems it was quite performant.
This looks to be 50% faster, and there is less allocations in log

This was added, but didn't see any use. For a large, complex chunk of
code we should have some users of it.
Remove all watch functionally from plugins, servers and packages.
