Make status printing look more like result printing.

[dmageeLANL]

Status tables can now be sorted. Addresses issue #705.

Code review checklist:

• Code is generally sensical and well commented
• Variable/function names all telegraph their purpose and contents
• Functions/classes have useful doc strings
• Function arguments are typed
• Added/modified unit tests to cover changes.
• New features have documentation added to the docs.
• New features and backwards compatibility breaks are noted in the RELEASE.md

[dmageeLANL]

• Moved function sort_results from commands/results.py to utils.py and renamed to sort_table, since it sorts the rows argument of the draw_table function.
• Changed the first argument of utils.sort_table from the entire args object to the value of args.sort_by (the key to sort on).
• Assign table title string to variable and include series name if applicable.
• In status_utils.print_status add sorter argument (use args.sort_by in commands/status.py when calling). In function status_utils.print_status, if sorter is given and is not false, use the same procedure as in commands/results.py:
  • Take the statuses list and make it into a list of flattened dictionaries.
  • Sort the list by the given key.
  • If sorter is not present just assign the new flat_sorted_statuses variable to the original 'statuses list and proceed as normal.

Now output is like this (snow):

I'm both bothered and amused by your serieses variable name.
