Fix sonar issues in SchemaGenerator
fixed formatting removed unused JanusGraph graph parameter deleted usage of print that were accompanied by a logger reduced loadSchemaIntoJanusGraph complexity by cutting it into smaller methods added private constructor to prevent instantiation optimized imports Change-Id: I4645a7fed266afbe6c2b21df20b40574aa9f31fd Issue-ID: AAI-1437 Signed-off-by: jczestochowska <justyna.czestochowska@nokia.com>
