EZP-31772: implement custom tag link

Currently, there is no UI for "link" custom tag attribute, so admin needs manually type location id.
Also, after admin typed it manually, it's still hard to say what's the content selected and be sure there is no typo in id.

I would like UI to contain:

• ability to select content
• ability to type link value manually
• display name of selected/typed object
  

TODO:

• Implement feature / fix a bug.
• Implement tests.
• Fix new code according to Coding Standards ($ composer fix-cs).
• Ask for Code Review.

Could you please release this simple solution while more complex #112 is in progress?

I worked on the frontend part (ezsystems/ezplatform-admin-ui#1213) and I assume your solution will work in a similar way. This will pass to the template just a string with ezlocation://2?

@dew326 Yes, it's just a UI change.
I hope it can be released as a fix while you're working on a more complete solution in ezsystems/ezplatform-admin-ui#1213 and #112
It looks like you still have work to do there to cover "display name of selected/typed object".
You know, community waiting for this for about 1 year already. Some of us building in-house solutions for this (cc: @AlexKhram), and it requires updates after each release, so it would make sense to have it in core ASAP to reduce time spending on things we'll have removed at some point.
What do you think? Can this be included in the next release, or would you be able to release ezsystems/ezplatform-admin-ui#1213 instead?

[dew326]

I think we don't plan to cover the case with displaying the content name as we wanted to keep it consistent with the regular link in AlloyEditor.

The question about if we can finish our solution is more for @adamwojs.

[ITernovtsii]

hm, so maybe it makes sense to include content name in regular link too? It was a helpful feature in legacy.

[dew326]

I think it might be a useful feature but let's do it step by step. Firstly we have to figure out if we can finish the "complex" solution.

Meantime we are going to make a separate bundle for this PR.
