We would have the UI for default language and time settign only for
user settings for now and not for realm-level settings because we
still need to migrate the backend to support the new model and will
be done in further commits.
This commit adds prefix paramter with value "user_" to the
settings_checkbox references in display_settings.hbs such
that ids are unique when we use display_settings.hbs for
realm-level settings UI.
This commit creates a new template user_display_settings.hbs
for user display settings and display_settings.hbs will be
used as a common template for user-level and realm-level
settings.
