This feature was requested long ago:

This MR is based off !253 but changed to use application settings and use wildcard strings
to give more flexibility in pattern matching. Regexps seemed overkill and easy to get wrong.

Only restrict e-mail addresses upon creation

Add new global application settings for default project and snippet
visibility levels.

Fix bug where error messages from Dropzone would not be displayed on the issues page

Closes #1258

Add checkboxes to the application settings page for restricted
visibility levels, and remove those settings from gitlab.yml.

Add the form-control CSS class to the feature checkboxes on the
application settings page to fix the vertical alignment with their
labels.  Also add aria-describedby attributes to form controls that have
a help text block.
