[Enhancement] Add findElementFromElement() and findElementsFromElement() commands

[beatfactor]

We need more user friendly commands which perform the equivalent of elementIdElement() and elementsIdElement but work more like findElement() and findElements(), accepting the same type of arguments.

syntax findElementFromElement() (find single):

const element = await browser.findElementFromElement('form', 'input');
console.log('element', element.getId());

const element = await browser.findElementFromElement({selector: 'form', index: 0}, 'input');
console.log('element', element.getId());

const element = await browser.findElementFromElement(by.css('form'), 'input');
console.log('element', element.getId());

const formElement = element('form'); // or element(by.css('form'));
const element = await browser.findElementFromElement(formElement, 'input');
console.log('element', element.getId());

syntax findElementsFromElement() (find multiple):

const elements = await browser.findElementFromElement('form', 'input');
elements.forEach(element =>  console.log('element', element.getId()));

I'm trying to implement exactly the same at least as a custom Nightwatch command, but faced a very strange issue #4273 - any ideas about why the issue happens and how to workaround it?

@beatfactor, if you implemented this feature on your side or at least have some progress with it, could you please share your progress here? Thanks!

Hey, if you're using v3, you can use the new element APIs for this: https://nightwatchjs.org/api/element/

Thanks! With the element API all works well without the issue, even on Nightwatch v2! Missed this feature before.
