The plugin will add OpenTracing instrumentation to Sharding-JDBC. This plugin makes it easy for developers using the Sharding-JDBC to incorporate the tracer that support OpenTracing.

There are two ways to incorporate io.opentracing.Tracer object(eg. Zipkin, Skywalking) with this plugin.

1. Get io.opentracing.Tracer object from Opentracing Tracer.
2. Invoke io.shardingjdbc.opentracing.ShardingJDBCTracer#init(io.opentracing.Tracer) before using Sharding-JDBC components.

You can set a tracer implement to the plugin by following instrument.

1. Set -Dshardingjdbc.opentracing.tracer.class=OPENTRACING_TRACER_CLASS_NAME to start the application. OPENTRACING_TRACER_CLASS_NAME MUST implement `io.opentracing.Tracer
2. Invoke io.shardingjdbc.opentracing.ShardingJDBCTracer#init() method before using Sharding-JDBC components.
