The system flag and extra table for that `ex_app_users` is removed to

This PR introduces our internal occ command for sending a request to
ExApp with notification about an event happened. The occ command is
needed to perform the HTTP request in a truly async maner not blocking
the original PHP process during request, that have to improve the user
experience.
The request is limited to 2s timeout, so that this occ command process
shouldn't live too long to not exceed the limits.
