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
* plugin/autopath: Add namespace selector and metrics
Add a namespace, so autopathing only is performed in this namespace.
This will make caching work for the cluster again.
Also export metrics that we've done a successful autopath
* dont shadow
* Fix
* Back the namespacing changes
* doc update
Go through all README and fix mistakes, extend example and let more
corefile snippets be test for validity.
* Cant use spefic addr in test
Add a full test server impl in this new package + tests. Move
dnsrecorder into this package as well and finish up the commented out
tests that were left in the old dnsrecorder package.
Update all callers and tests.
* Rename middleware to plugin
first pass; mostly used 'sed', few spots where I manually changed
text.
This still builds a coredns binary.
* fmt error
* Rename AddMiddleware to AddPlugin
* Readd AddMiddleware to remain backwards compat
