Feature request: ability to specify unpublished page

[lufog]

Need ability to specify unpublished page, like in error plugin. Because if we for example switch the language on the maintenance page, \maintenance will appear in the url. Now even if we turn off the maintenance mode, the user will still remain on the maintenance page.
And in general it is not good when the user can get access to this page when the maintenance mode is disabled.

I will clarify what happens if you specify your own maintenance page in the plugin settings.
