Miek Gieben bfaf9e0aec core: add more transports (#574 )

* core: add listening for other protocols

Allow CoreDNS to listen for TLS request coming over port 853. This can
be enabled with `tls://` in the config file.

Implement listening for grps:// as well.

a Corefile like:

~~~
. tls://.:1853 {
    whoami
    tls
}
~~~

Means we listen on 1853 for tls requests, the `tls` config item allows
configuration for TLS parameters. We *might* be tempted to use Caddy's
Let's Encrypt implementation here.

* Refactor coredns/grpc into CoreDNS

This makes gRPC a first class citizen in CoreDNS. Add defines as being
just another server.

* some cleanups

* unexport the servers

* Move protobuf dir

* Hook up TLS properly

* Fix test

* listen for TLS as well. README updates

* disable test, fix package

* fix test

* Fix tests

* Fix remaining test

* Some tests

* Make the test work

* Add grpc test from #580

* fix crash

* Fix tests

* Close conn

* README cleanups

* README

* link RFC

erratic

erratic is a middleware useful for testing client behavior. It returns a static response to all queries, but the responses can be delayed by a random amount of time or dropped all together, i.e. no answer at all.

._<transport>.qname. 0 IN SRV 0 0 <port> .

The erratic middleware will respond to every A or AAAA query. For any other type it will return a SERVFAIL response. The reply for A will return 192.0.2.53 (see RFC 5737), for AAAA it returns 2001:DB8::53 (see RFC 3849).

Syntax

erratic {
    drop AMOUNT
}

AMOUNT drop 1 per AMOUNT of the queries, the default is 2.

Examples

.:53 {
    erratic {
        drop 3
    }
}

Or even shorter if the defaults suits you:

. {
    erratic
}

Bugs

Delaying answers is not implemented.
