Add embedded monitoring with simple-jmx-exporter-agent.

* simple-jmx-exporter-agent.jar is added as a javaagent.
* MBeans to collect are defined in `tomcat-metrics.xml`
* for backward compatibility, metrics are outputted in a file (`$log_dir/tomcat7-metrics.data`) which is collected by `stats-appstat` script (with a simple `cat` command)

**Pending**
* verify that the unit of durations metrics returned by `stats-appstat` is mills and not seconds (e.g. `threads.cputime`)
* release simple-jmx-exporter-agent.jar and update its URL in `MakeFile`
