Drush, Views and Page Manager
There is drush views-revert, which alone will give you a list of views to revert, or can also take multiple views names as arguments, as in drush vr archive frontpage.

So far, nothing like that exists for Panels.

However, if you were to use the Features module to export the Views and Panels, instead of a custom module, you could use the drush commands that Features provides.
