Allow disabling AdGuard DNS protection for a period of time

It's not likely that a user would want to disable protection for the entire account indefinitely, and is more than likely used for resolving issues in the short term, such as a problematic website or app.

It would be good to be able to disable protection for a period of time instead, having it enable automatically after that time period had ended.

Although the below application is not directly applicable to this feature request, it gives a general idea of what I mean.
