Complete Test Suite #7
Description
An initial implementation of a JUnit test suite for the EdgeApplicationAuthenticator has been added.
The TesterConfiguration class has been also added to keep a centralized management of testing variables and keys.
We should implement the same approach also for the EdgeApplicationConnector in order to easily test all the library feature for the new releases. Ideally we can move/copu code from the OpenNessConnectorTester from the main repository folder to the test folder.
