Created a new uima-as component to capture runtime metrics of uima-as services. The monitor
connects to a JMX server via provided URI and begins checkpoints at a given intervals each
time collecting metrics from JMX service beans. The monitor supports plug in listener that
are notified each time the checkpoint is done. The listener receives the metrics for the current
checkpoint (interval). The listener can format the metrics to specific requirements.

> In complex uima-as deployments it is hard to find bottlenecks which need scaleup. A JMX-based
monitor is needed to collect runtime metrics from every uima-as service. The metrics must
include idle time, queue depth, amount of time each service waits for a free CAS. The monitor
should be an embeddable component that can be deployed in a java application. The monitor
should allow custom formatting of metrics via pluggable extension.
