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
