vspd: Create shutdown context earlier.

Browse Source 
Create the shutdown context earlier so process begins handling shutdown
signals earlier. Specifically, the context should be created before
creating any resources which need a graceful shutdown such as the
database. This is important because without explicit signal handling the
process will terminate immediately upon receiving a signal without
running deferred tasks.
