Merge ~jocave/plainbox-provider-snappy:add-summaries into plainbox-provider-snappy:master

[Jonathan Cave]

Identified some key jobs called in test plans that where missing summaries. Generally switched already short `_description` fields to `_summary` and if longer then add a new `_summary`.

Tested the improvement by running list-bootstrapped on various test plans.

+1.
I see I'm guilty of omitting summaries in the past too.
