Expose maxParallelDefault for global override

      Description

      We may want to be able to override maxParallel globally on server startup, in particular as this will make it easier to run benchmarks with maxParallel default value changed (i.e., we don't want to change this for each and every query).

        See branch https://github.com/SYSTAP/bigdata/pull/433 – running through CI now.

        It is now possible to set the system default as follows:

        > -Dcom.bigdata.bop.PipelineOp.maxParallel=20

        Query hints etc. will still override this default, so this is just the base setting (which eases benchmarking, as it avoids touching all the queries).

        Will merge down once CI is green.
