QPID-4636: expand testing of the new TrustManagers

- Removes the 'app2' cert from the test broker peer store so it only contains the 'app1' cert.
- Add a java broker trust store (currently continues to match client trust store, contans the test CA).
- Add a java client keystore with a completely untrusted cert.
- Add additional unit testing of QpidPeersOnlyTrustManager inc use of otherwise trusted certs, and completely untrusted certs.
- Add additional unit testing of QpidMultipleTrustManager and its behaviour when wrapping a regular TrustManager, a QpidPeersOnlyTrustManager, and both at once.
- Add system tests showing a client with untrusted SSL cert failing to connect, then succeeding when adding it to the peerStore on the broker.

Work by myself and Michal Zerola.
