用于收集Java日志到Redis或者Kafka中，日志收集完之后可使用Logstash导入ELK栈中分析

##logback ###redis -- pom.xml添加依赖

    <dependency>
        <groupId>net.myscloud.plugin</groupId>
        <artifactId>logging-appender</artifactId>

-- logback.xml添加Appender

<appender name="Redis" class="net.myscloud.plugin.logging.logback.redis.appender.LogbackRedisAppender">

        <source>test-application</source>
