This was hard to do previously as we didn't hardcode this in the source,
but now with OWNERS files we can just generate this list.
Privacy wise this isn't worse than being listed in OWNERS file in the
first place. And it's a nice hat tip to the people making CoreDNS
better.

* Remove context.Context from request.Request
This removes the context from request.Request and makes all the changes
in the code to make it compile again. It's all mechanical. It did
unearth some weirdness in that the context was kept in handler structs
which may cause havoc with concurrently handling of requests.

This mechanism defeats the purpose any plugin (mostly) caching can still

It was only actually used in kubernetes; and there specifically would
mean any network hiccup would NACK the entire server health.

Add a ready plugin that allows plugin to signal when they are ready.
Once a plugin is ready it is not queried again.
This uses same mechanism as the health plugin: each plugin needs to
implement an interface.
Implement readines for the *erratic* plugin to aid in testing.
Add README.md and tests moduled after the health plugin; which will be
relegated to just providing process health. In similar vein to health
this is a process wide setting.
With this Corefile:
~~~
. {
erratic
whoami
ready
}
bla {
erratic
whoami
}
~~~
ready will lead to:
~~~ sh
% curl localhost:8181/ready
% dig @localhost -p 1053 mx example.org
% curl localhost:8181/ready
OK%
~~~
Meanwhile CoreDNS logs:

*ready* can be used in multiple server blocks and will do the right
thing; query all those plugins from all server blocks for readiness.
This does a similar thing to the prometheus plugin.
