Require essential proxybackend fields

[jykae]

Closes #1562
Closes #1816

• require essential proxybackend fields, regex validation kicks in only when field has some input

@jykae Notification worked before too. I detected another problem and required fields don't resolve it.
Steps:

1. Go to any API and open Proxy tab
2. Click on Delete button, if there are any information
3. Don't fill a form and click on Save&Publish button

Found result: Submit hook isn't end, button is disable, no one notification about required fields
Expected result: Notify users about required fields and button must be available

Should I create another issue or you will fix in this repo?

@marla-singer good find, I'll check after lunch 🍽

@marla-singer There is open issue on autoform about this Meteor-Community-Packages/meteor-autoform#1442 I try to call that validateForm if it makes any difference, as @abecks suggests so.

EDIT: no difference, returns also true for me. Trying to think something..

@jykae I had the same situation when worked on monitoring feature. I did the handle check on insert/update hook
https://github.com/apinf/platform/blob/develop/monitoring/client/autoform.js#L16

@marla-singer Well, it's not beauty but I think it checks now all "required" fields have values. Maybe I should add star for required field labels in addition to showing error message.

EDIT: seems like there's separate issue for that #1171

[jykae]

@marla-singer could you check if this fixes now issue with empty fields? I would like to leave the star issue as enhancement, I don't know that much of CSS magic.

@jykae Works 👍 I couldn't merge it because of console log in code so I afforded to delete it

@marla-singer 🆒 and thanks for contribution 🎉
