Logback groovy configuration add support for Perf4j 
----------------------------------------------------

                 Key: LBCORE-252
                 URL: http://jira.qos.ch/browse/LBCORE-252
             Project: logback-core
          Issue Type: Improvement
          Components: Appender
            Reporter: Muyen Lee
            Assignee: Logback dev list
            Priority: Minor


I want to add an AsyncCoalescingStatisticsAppender. The XML confugration looks like this.

<appender name="CoalescingStatistics" class="org.perf4j.logback.AsyncCoalescingStatisticsAppender">
        <param name="TimeSlice" value="60000"/>
        <appender-ref ref="graphExecutionTimes"/>
        <appender-ref ref="graphExecutionTPS"/>
        <!-- We add the JMX Appender reference onto the CoalescingStatistics -->
        <appender-ref ref="perf4jJmxAppender"/>
    </appender>

logback.groovy's appender function doesn't support <appender-ref ref="perf4jJmxAppender"/>

The workaround is to write groovy directly

JmxAttributeStatisticsAppender jmxAppender = new JmxAttributeStatisticsAppender()
jmxAppender.name = "Per4j"
jmxAppender.context = context
jmxAppender.tagNamesToExpose="tag1, tag2"
appenderList.add(jmxAppender)

AsyncCoalescingStatisticsAppender coalAppender = new AsyncCoalescingStatisticsAppender()
// in millisecond
coalAppender.timeSlice=10000
coalAppender.name = "CoalescingStatistics"
coalAppender.context = context
coalAppender.addAppender(jmxAppender)
appenderList.add(coalAppender)
