Reinstate product groups

[WalterKolczynski-NOAA]

Description

Testing with full-sized GEFS found that the sheer number of tasks overloads rocoto, resulting in rocotorun taking over 10 min to complete or hanging entirely. To reduce the number of tasks, product groups are reimplemented so that multiple forecast hour are processed in a single task. However, the implementation is a little different than previously.

The jobs where groups are enabled (atmos_products, oceanice_products, wavepostsbs, atmos_ensstat, and gempak) have a new variable, MAX_TASKS, that controls how many groups to use. This setting is currently per member. The forecast hours to be processed are then divided into this many groups as evenly as possible without crossing forecast segment boundaries. The walltime for those jobs is then multiplied by the number of times in the largest group. For the gridded wave post job, the dependencies were also updated to trigger off of either the data being available or the appropriate segment completing (the dependencies had not been updated when the job was initially broken into fhrs).

A number of helper methods are added to Tasks to determine these groups and make a standard metatask variable dict in a centralized location. There is also a function to multiply the walltime, but this may be better off relocated to wxflow with the other time functions.

As part of switching from a single value to a list, hours are no longer passed by rocoto as zero-padded values. The lists are comma-delimited (without spaces) and split apart in the job stub (jobs/rocoto/*), so each j-job call is still a single forecast hour.

The offline post (upp) job is not broken into groups, since it really isn't used outside the analysis anymore.

I have no major concerns with this PR. It looks good and clean to me. I have not created the XML and looked at it or run any tests.

A few comments inline with the review.

[KateFriedman-NOAA]

Changes look good, just leaving a few suggested changes to resolve some typos I noticed.

[WalterKolczynski-NOAA]

All reviewer comments other than the location of test methods have been addressed, so I am going to go ahead and run CI for the first machine.

[WalterKolczynski-NOAA]

Need to look at the gempak jobs a little closer.
