HONEYCOMB-145 - Utility Class Refactoring
problematic mockito-all changed to mockito-core( https://github.com/mockito/mockito/issues/324) Translate Utils Splitted to multiple Trait Interfaces Ipv4Translator - Logic for translation of ipv4-based data Ipv6Translator - Logic for translation of ipv6-based data MacTranslator - Logic for translation of mac-based data AddressTranslator - Aggregation trait for Ipv4/Ipv6/Mac JvppReplyConsumer - Logic for extracting replies from jvpp calls ByteDataTranslator - any byte-based conversions Plus some existing utility classes changed to traits Change-Id: I342b625954223966802e65dca0fabf8456c89345 Signed-off-by: Jan Srnicek <jsrnicek@cisco.com>
