James Hartig a469a17cdf Instead of hardcoding plugin lists in autopath/health, use interfaces. (#1306)
Switched health and autopath plugin to allow any plugins to be used instead
of a hardcoded list. I did not switch federation over since it wasn't
obvious that anything other than kubernetes could be used with it.

Fixes #1291

# health
*health* enables a simple health check endpoint.
By default, it listens on port 8080.
## Syntax
~~~
health [ADDRESS]
~~~
Optionally takes an address; the default is `:8080`. The health path is fixed to `/health`. The
health endpoint returns a 200 response code and the word "OK" when CoreDNS is healthy. It returns
a 503. *health* periodically (1s) polls plugin that exports health information. If any of the
plugin signals that it is unhealthy, the server will go unhealthy too. Each plugin that
supports health checks has a section "Health" in their README.
## Plugins
Any plugin that implements the Healther interface will be used to report health.
## Examples
Run another health endpoint on http://localhost:8091.
~~~ corefile
. {
health localhost:8091
}
~~~
