Override timeout on process_check_run

[agritheory]

In cases where a lot of checks need to be processed, the default nginx timeout that frappe provides (120 seconds) may not be enough.

Potential strategies:

• restructure so that a return value is sent after the process is enqueued
• Allow the realtime function to continue updating
• Force update when it completes

As best I can find, Frappe does not provide a place to override the timeout value on a request in the client, like in frappe.call, which is too bad. This likely wouldn't override the nginx setting anyway.
