This PR adds debug support for failed lookups. I.e. when a record
is outside the configured domain, we do a forward lookup. If this
fails the error is silently dropped. This PR adds it back as an error
in when debugging is enabled.
Fixes#197
* middleware/etcd: reverse addresses
Implement reverse (PTR) addresses. Update the documentation on how to
configure test. Added tests as well.
Fixes: #157#159
* Cleanup readme a little
With this you can retreive the raw data that the etcd middleware
used to create the reply. The debug data is put in TXT records
that are stuffed in the CH classs. This is only enabled if you
specify `debug` in the etcd stanza.
You can retrieve it by prefixing your query with 'o-o.debug.'

Return a delegation when seeing one while traversing the tree in

Put the SOA and NS record in the zone.Apex as these are to be handled
somewhat special.
Lowercase record on insert to make compares easier. This lowercases
all RR that have domain names in their rdata as well.
