Fix historyId to be dependent on dynamic allure parameters #743

What is the current behavior?

Parameters added via the allure.dynamic.parameter inside a test body don't affect allure history of the test.

If the current behavior is a bug, please provide the steps to reproduce and if possible a minimal demo of the problem

Run the following example multiple times to produce multiple *-result.json files:

import allure
import time

def test_issue743_reproduction():
    allure.dynamic.parameter("time", time.perf_counter())

These results all have the same historyId. In such a case allure reporter shows us only one test case with several retries:

What is the expected behavior?

There should exists one test case per run, each with no retries in a way, similar to native pytest parameters.

  1. Take the nodeid of a test.
  2. Take all dynamic parameters of the test with excluded set to False.
  3. Sort the parameters alphabetically by their names (historyId should not depend on parameters order).
  4. Append a string representation of the values to the nodeid (use some separator to prevent collisions with other tests).
  5. Calculate hash of the resulting string and use it as historyId.
