Improve LicenseManagerImpl implementation
- Use STAX API for XML processing instead of parsing it manually - Rearrange code for clarity and testing - Adjust JUnits accordingly Issue-ID: APPC-1024 Change-Id: I9d655b581adb401b0c20bc29eda6a2bce1f2ef89 Signed-off-by: Joanna Jeremicz <joanna.jeremicz@nokia.com>
