Ability to add tags for tests

### Contribution

- [ ] I'd be willing to implement this feature ([contributing guide](https://github.com/gemini-testing/hermione/blob/master/CONTRIBUTING.md))

### Describe the user story

### Describe the solution you'd like

I need to label my tests with tags so that I can later filter the tests by these tags in the report. For example,

```js
testplane.setTag(['smoke', 'desktop']);
it("some smoke test", async ({browser}) => {});

testplane.setTag('experiment');
it("some experiment", async ({browser}) => {});
```

and in the HTML-report labels (like in GitHub issues) can be displayed for each test. Clicking on them should filter the test tree
