Protect MsgClient via SSL (ink Client Authentication)

- Add Component to create SSLContexts with own Key- and trust store.
- Inject SSLContext into HTTP Client.
- Add EAAF-Components Core Dependency, which is needed by
  SSLContextCreator (KeyStoreUtils).

Schema Changes in mzs:DeliveryRequest/Config:
- Got Rid of mzs:DeliveryRequest/Config/Server. In mzs 1.4.1,
  Server replaces the result of zkopf query person request. Since this
  zkopf interface does not exist anymore, Server was removed.
- Add ClientType, which holds all parameters needed to connect to a
  service (Url, SSL params, a.o.).

Configuration:
- Add default parameters for SSL Clients in application.yaml.
- Merge default parameters into incoming mzs:DeliveryRequests.

MoaZSException Fixes:
- Remove "Extends throwable" from Builder.
- Add convenient shorthand init method (message, throwable).

Refactor:
- Put "determinePath" to FileUtils.
- Put string related utility functions into StringUtils.
