Extend the page fault action INI to handle following:
1) Ignore page fault event
2) Trigger SSR on page fault threshold
3) Send blob of data to userspace on page fault threshold
On pagefault wakeup event, save per symbol pagefault timestamp
and once the event count reaches configured threshold within the
configured time interval, either trigger SSR or notify userspace
with pagefault address and count based on INI configuration.
