Every plugin needs to deal with EDNS0 and should call Scrub to make a
message fit the client's buffer. Move this functionality into the server
and wrapping the ResponseWriter into a ScrubWriter that handles these
bits for us. Result:
Less code and faster, because multiple chained plugins could all be
calling scrub and SizeAndDo - now there is just one place.
Most tests in file/* and dnssec/* needed adjusting because in those unit
tests you don't see OPT RRs anymore. The DNSSEC signer was also looking
at the returned OPT RR to see if it needed to sign - as those are now
added by the server (and thus later), this needed to change slightly.
Scrub itself still exist (for backward compat reasons), but has been
made a noop. Scrub has been renamed to scrub as it should not be used by
external plugins.
Fixes: #2010

* plugin/dnssec: add per server metrics
final plugin.
Fixes#1696#1492#1189
* Move cache cap into handler so we can access the server label
* Remove cache-capacity from it entirely
* update docs
* plugins: use plugin specific logging
Hooking up pkg/log also changed NewWithPlugin to just take a string
instead of a plugin.Handler as that is more flexible and for instance
the Root "plugin" doesn't implement it fully.
Same logging from the reload plugin:

* update docs
* better doc
* Update all plugins to use plugin/pkg/log
I wish this could have been done with sed. Alas manually changed all
callers to use the new plugin/pkg/log package.
* Error -> Info
* Add docs to debug plugin as well
* plugin/dnssec: implement shotgun from CloudFlare
Put a whole bunch of types in the NSEC bitmap and remove the one that's
being asked for.
Add more records for queries to the apex, SOA, DNSKEY, MX.
* 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
