Expected Behavior:

When creating an options page using \new_cmb2_box() give ability to define the autoloader, so devs could define that those options should NOT be autoloaded.

As a developer, you know the drawbacks of autoload=yes.

Actual Behavior:

currently it defaults to yes

Steps to reproduce (I have confirmed I can reproduce this issue on the trunk branch):

Use the https://github.com/CMB2/CMB2-Snippet-Library/blob/master/options-and-settings-pages/options-pages-with-tabs-and-submenus.php snippet and save options.
