Allow scheduled execution of multi-session apps

This will probably require Livebook Teams, as we need storage to uniquely coordinate runs across long time spans. If you have a use case for this feature, please drop a comment below.

I totally agree this could be a Teams feature @josevalim @hugobarauna.

This is a very useful feature when you have a notebook that executes some data analyses and then reports it to a Discord/Slack chat.

For example, imagine you have a job that checks every day how many orders have succeeded, and you want to report this to your sales team at the end of the day.
