Title: JVM agent sending generic VM metrics:  make sure they are reported as JVM metrics

This is really a bugfix, because with the default settings a Java JVM sFlow agent could easily cause gmetad to create a large number of RRDs -- analogous to a hypervisor with a large and growing number of VMs. This commit prevents that from happening, and pulls the JVM metrics together in a more explicable and readable way.

In a separate, minor bugfix, the VM memory utilization % metric was being reported with slope=ZERO (constant) instead of slope=BOTH (gauge). Now it is given it's own RRD chart.
