Add NOVA_SHUTDOWN_TIMEOUT variable
This adds a variable to control the [DEFAULT]/shutdown_timeout
config in nova to control whether or not a guest should have
a graceful shutdown of the OS or if it should just stop
immediately (no timeout). Since devstack uses CirrOS images
by default, the default value for the NOVA_SHUTDOWN_TIMEOUT
variable is 0 which should speed up tempest runs. The default
in nova.conf [1] is 60 seconds.
