The "db show -format=json" was missing newline at the end. While
at it, switch to MarshalIndent for nicer output and extend the tests.

Hive dependency is bumped to add the -scripttest.update support.

43587d4 broke JSON marshalling of Status by introducing a separate statusJSON
type and Unmarshal{JSON,YAML} methods, but didn't introduce the Marshal{JSON,YAML}
methods, which caused dictionary key mismatches as Status struct was used to marshal
instead of statusJSON.

Fix this by removing the whole statusJSON construct and add json and yaml tags to Status.
There is no need for filling in the `id` field when unmarshalling Status as this is completely
internal to the reconciler.
