api/uniter: ReadSettings to use params.Settings

Instead of map[string]interface{}, ReadSettings()
now returns the more appropriate params.Settings
type (map[string]string), since all settings are
stored and checked as strings. This is a prereq
step to migrating the uniter worker to using the
API.

Please take a look.

Please ignore the added files - I merged trunk, but didn't specify all these
changes as a prereq. All added files already landed in trunk in
https://codereview.appspot.com/13512049/.
