/**
 * @module KvObjectEditor
 * KvObjectEditor components are called in FormFields when the editType on the model is kv.  They are used to show a key-value input field.
 *
 * @example
 * ```js
 * <KvObjectEditor
 *  @value={{get model valuePath}}
 *  @onChange={{action "setAndBroadcast" valuePath }}
 *  @label="some label"
   />
 * ```
 * @param {string} value - the value is captured from the model.
 * @param {function} onChange - function that captures the value on change
 * @param {function} [onKeyUp] - function passed in that handles the dom keyup event. Used for validation on the kv custom metadata.
 * @param {string} [label] - label displayed over key value inputs
 * @param {string} [labelClass] - override default label class in FormFieldLabel component
 * @param {string} [warning] - warning that is displayed
 * @param {string} [helpText] - helper text. In tooltip.
 * @param {string} [subText] - placed under label.
 * @param {string} [keyPlaceholder] - placeholder for key input
 * @param {string} [valuePlaceholder] - placeholder for value input
