OPENDJ-1307 Migrate server ASN1 classes to SDK


ASN1 classes logging is throwing an UnsupportedOperationException while being used in the server. This exception is thrown by OpenDJLoggerAdapter from the opendj-slf4j-adapter in use in the server.
Changed OpenDJ SDK to use LocalizedLogger instead of raw slf4j-api (at least for IO category).
More work remains to switch all OpenDJ SDK to use LocalizedLogger instead of raw slf4j-api.


StaticUtils.java, *.java:
Removed IO_LOG + replaced every uses of it by using per class LocalizedLoggers.

pom.xml:
Added a compile time dependency to 18n-slf4j.

OpenDJLoggerAdapter.java:
Removed an empty line.
