Breaking API Changes

util-logging: The namespace forwarders for Level and Policy in com.twitter.logging.config
have been removed. Code should be updated to use com.twitter.logging.Level and
com.twitter.logging.Policy where necessary. Users are encouraged to use 'util-slf4j-api' though
where possible. 6ab4aeac
util-logging: The deprecated com.twitter.logging.config.LoggerConfig and associated
classes have been removed. These have been deprecated since 2012. Code should be updated
to use com.twitter.logging.LoggerFactory where necessary. Users are encouraged to use
'util-slf4j-api' though where possible. 5d43773e
