ref(postgres): move username and password to secrets

[kmala]

closes #18

[bacongobbler]

looks like from the tests the container isn't running: https://travis-ci.org/deis/postgres/builds/108866748

[bacongobbler]

Hmm, I understand now. It's because in the tests we don't have /etc/secret-volume/user available in the container. I'll see if I can come up with a fix.

@kmala I found that this works with the following patch:

diff --git a/contrib/ci/test.sh b/contrib/ci/test.sh
index 5e25a24..1a54565 100755
--- a/contrib/ci/test.sh

+# make sure we are here
+CURRENT_DIR=$(cd $(dirname $0); pwd)

+mkdir -p tmp
+echo "testuser" > tmp/user
+echo "icanttellyou" > tmp/pass
+JOB=$(docker run -dv $CURRENT_DIR/tmp:/etc/secret-volume $1)
 # wait for postgres to boot
 sleep 10
 docker exec $JOB is_master

also need to create .gitignore with contrib/ci/tmp in there and this should pass CI.

You'll also want to merge the two commits into one. Thanks! :)

I'm going to close this, but your work lives on in #36. Thanks!
