  cache_fetch: Fix MI tree format

The MI "cache_fetch" command was building a poorly formatted MI tree
(viz below). We fix the command tree format in order to make the
resulting data easier to digest programatically.

Old MI tree format visualization:
    'NULL: "out_key: [out_value]"'

New MI tree format visualization:
    '"key": "out_key", "value": "out_value"'

Fixes #1298
