Fixes; SSL Client Auth Works!

- Switch to java 12 for now. Reason: Bug [1] in JDK 11 (up to
  jdk-11+28) impairs SSLHandshake ("Unsupported Operation Exception"),
  but was fixed in Java 12.
- Set HTTP policy to infinite.
- Fix key/truststore path resolution
- Fix NPE in ConfigUtil.merge
- Rearrange application.yaml to include two config profiles (one with
  and one without SSL for the msg client).
- Add key material for testcases (Note: expires: May 2 14:47:08 2020 GMT)
- Update MsgClient Testcases
