Use pagination when updating CrisMetric records in index

[kshepherd]

The UpdateCrisMetricsInSolrDocService update method tries to read all metrics at once before processing and updating the index.
In a system with a very large number of CrisMetrics DB rows, this can cause heap space errors.

This small PR adds a default page size of 1000 and reads pages in a while loop.
