func_documentation_string: Return a promise that resolves to the same value as the given promise. If it takes more than the
  specified delay to do so, the returned promise instead rejects with a timeout error.
  
  @param {Promise<*>} promise The promise to resolve.
  @param {Number} delay The millisecond delay before a timeout occurs.
  @param {String|Error=} message The error message or Error object to reject with if the operation
  times out.
  @return {Promise<*>} The promise that times out.
