Form labels help icon change

Hello

a PR [1] changing the form labels help icons was merged yesterday and will be
part of upcoming 1.15 release. The change moved icons with popover help from
right of the form field to the field label. If you're author of plugin that
extends Foreman UI by fields with such help, you might want to update your
plugin to avoid UI mismatches, see screen shot [2] for illustration.

Good examples can be found at the original PR or plugin PRs I sent to REX [3],
discovery [4] and tasks [5]. Openscap, docker did not seem to need it. Katello
seems to have such help next to value (subscription info) and does not use
core helpers.

If you need help with you plugin, please let me know.
