Show financial figures to two decimal places

[Iain-S]

For rctab sub summary, and possibly other commands, we output the raw data as returned by the server. This means that financial figures are shown to many decimal places:

rctab sub summary --subscription-id 1234z-1234a-1234b-1234c
[
    {
        ...
        "total_cost": 78.18015651709896
    }
]

However, it would be nice to either:

a. Show figures to to two decimal places by default, or
b. Show some shell trick to accomplish the same thing.

a. Can be achieved by placing item["total_cost"] = round(item["total_cost"], 2) After item.pop("role_assignments")
