Ability to configure fields on new group screen

[cairocoder01]

Is your feature request related to a problem? Please describe.
When configuring fields for groups, these is not a way to configure what fields show by default on the new group screen. For contacts, that can be configured in the fields admin (see screenshot below). The same does not show up for groups.

Describe the solution you'd like
Show same selection to configure fields on new group screen like you can for contacts.

Describe alternatives you've considered
Alternately, just put this in the new Customizations admin
