The testhook post-test hooks only work if you use a TestMain to
invoke them, otherwise the cleanups can be registered but never
actually get run. This deletes the etcd sockets, and temp
directories, that we created from our test runs. We also fix
the test creating a temp file directly to create it in a TempDir
(which gets cleaned up after the test), and fix the name of the
top-level tests displayed in TestMain.
i used this script, a little clunky but it got the job done
```bash
for file in `find . -type f -print | grep '\.go'`; do
sed '1,/^\/\/ limitations under the License.$/d' $file > $file.tmp;
result=`cat $file.tmp`
if [[ result != "" ]]; then
gofmt $file.tmp &> /dev/null;
if [[ $? == 0 ]]; then
mv $file.tmp $file && gofmt -w $file;
else
rm $file.tmp;
fi
else
rm $file.tmp;
fi
done
```
