Phase 1 of MOBSDK-655. Removed workflowInfo from AlfrescoSession and removed session from all initWithProperties methods for model objects.
Phase 2: AlfrescoRepositoryInfo and AlfrescoRepositoryCapabilities are now generated by the AlfrescoRepsoitoryInfoBuilder class. Also fixed some issues with parsing IDs on 3.4 servers introduced in previous commit.
Phase 3 of MOBSDK-655: Consolidated previous services into single AlfrescoWorkflowService.
Final phase 3 of MOBSDK-655: Renamed several methods to follow Apple naming conventions and to be consistent with Android WorkflowService.
