Increase junit coverage in ONAP-logging

Added some junit tests to increase coverage of ONAP-logger.
Many classes still need test cases.

Also fixed some sonar issues:
Returned interface instead of ConcurrentHashMap.
Used EnumMap instead of HashMap.
Used StringBuilder instead of StringBuffer.
Replaced literals with constants.
Replaced enum1.toString().equals(enum2.toString()) with enum1 == enum2

Updated license dates.
Updated another license date.
