lookup_plugins: loop over hashes
Create a lookup plugin named dict that can be used to loop over hashes. It converts a dict into a list of key-value pairs, with attributes named "key" and "value." Also adds a brief explanation and simple example to the docs. Signed-off-by: Kent R. Spillner <kspillner@acm.org>pull/5964/head
