Class for running scheduled jobs to execute a jmap heap histogram and load the results into
the {@link InternalStatisticsReceiver}. This is for use in identifying memory issues at run time
by capturing a regular snapshot of both the number of instances of classes and the bytes in use.
<p>
As with all internal statistics it is reliant on the stat key being configured in stroom properties
(i.e. stroomCoreServerPropertyContext
