Minor updates to the OnosMetrics API:

 * Modified method OnosMetrics.registerMetric() to return the registered
   metric, and use Generics to specify the Metric return type.
   Thus, we can allocate and register a gauge when the gauge is declared. E.g.:

class Foo {
    private Final Gauge<Long> gauge =
        OnosMetrics.registerMetric(COMPONENT, FEATURE, "MyGauge",
            new Gauge<Long() { ... });

Also, minor updates to some of the Javadoc text.
