docs: Get action type constant for a sync action. It uses UPPER_SNAKE_CASE and combines feature name and action name.
  @param {string} feature - The feature name of the action.
  @param {string} action - The action name.
  
  @example
  const utils = require('rekit-core').utils;
  utils.getActionType('home', 'doSomething');
  // => HOME_DO_SOMETHING
