Currently, when you run `TestEtcdCredentials` at etcd_credentials_test.go multiple times without clearing data of etcd, you will get following errors.
```
etcd_credentials_test.go:38: Failed to create root role: etcdserver: role name already exists
etcd_credentials_test.go:41: Failed to create user: etcdserver: user name already exists
```

This should be enough to show it in pull request; unless github has
something against symlinks.

When a query, different from a TXT lookup is performed, all services
with a missing `Host` field should be filtered out, as these otherwize
cause a line in the answer section with a single dot (`.`) as the
result. This behavior manifests for example when a TXT record is present
on a domain, eg. an A or SRV lookup is performed on said domain.
If there are no services containing a `Host` field, a `NODATA` response
should be given. If there are other Services, these alone should be
returned for the query.
Filter any service that has an empty Host field from all lookup types
other than TXT to solve this issue. At the same time the check for empty
`Text` fields in TXT queries are also moved to the same check in the
etcd ServiceBackend.

There are string ttls at commands at README.md.
But because `TTL` of `Service` is uint32, commands at README is wrong.
e.g.) `etcdctl put /skydns/local/skydns/x1 '{"host":"1.1.1.1","ttl":"60"}'`.
The `b` struct is just copying all the fields into a new one, to
check if it already existed in a set. This isn't needed as all the
fields are identical, and a small rearrangement of the code solves the
same problem without the copy.
The check is done through
```
if [[ $(go list -f '{{ join .Deps " "}}') == *" testing "* ]]; then
error..
fi

This fix deprecates endpoints for out-of-cluster k8s api,
The Corefile still takes multiple endpoints though only

* Default to upstream to self
This is a backwards incompatible change.
This is a massive (cleanup) PR where we default to resolving external
names by the coredns process itself, instead of directly forwarding them
to some upstream.
This ignores any arguments `upstream` may have had and makes it depend
on proxy/forward configuration in the Corefile. This allows resolved
upstream names to be cached and we have better healthchecking of the
upstreams. It also means there is only one way to resolve names, by
either using the proxy or forward plugin.
The proxy/forward lookup.go functions have been removed. This also
lessen the dependency on proxy, meaning deprecating proxy will become
easier. Some tests have been removed as well, or moved to the top-level
test directory as they now require a full coredns process instead of
just the plugin.
For the etcd plugin, the entire StubZone resolving is *dropped*! This
was a hacky (but working) solution to say the least. If someone cares
deeply it can be brought back (maybe)?
The pkg/upstream is now very small and almost does nothing. Also the
New() function was changed to return a pointer to upstream.Upstream. It
also returns only one parameter, so any stragglers using it will
encounter a compile error.
All documentation has been adapted. This affected the following plugins:
* etcd
* file
* auto
* secondary
* federation
* template
* route53
A followup PR will make any upstream directives with arguments an error,
right now they are ignored.

* Remove version pinning of thrift, ugoriji/go, and etcd
For incompatibility reasons at one point, we were forced
to pining the version of thrift, ugoriji/go, and etcd
to very specific versions (some are not versioned commits)
to get around the build issues.
It looks like those incompatibility issues are gone so
we could remove the pinning of thrift, ugoriji/go, and etcd.
