Add twig function to get assigned element tags

[skoch98]

I've implemented a blog on my website and desiceded to tag a blog post via pimcore tags.

When I tried to output the tags in my tempalte I was faced with a small problem. I didn't know any way to access them on twig side. Neither the documentation as well as the core code provided me with any existing solution.

In the Pimcore demo the "Event" object using a multiselect as tag-solution - but that's not an option for me...

I was wondering why there is no getTags method in Pimcore\Model\Element\AbstractElement. Is there a reason for this? The data can easily be loaded asynchronously, only when the getter is called, so there is no disadvantage. WDYT?

Because this is unclear to me, and I already implemented a solution that works without core editing - I decided to write a new Twig function and I want to share it here for discussion.

Personally, I prefer it if there would be a getTags method.
