Look up stuck-in-rebooting instances in manager

The poll_rebooting_instances() method for a virt driver can be
called periodically from the manager to handle instances that
may be stuck in a rebooting state. The only information passed
to the virt driver is the configured timeout, which means any
driver implementing this will have to do the same database
query: db.instance_get_all_hung_un_rebooting (..., timeout).

This patch makes the manager do this before calling the virt
driver, passing the appropriate set of instances, which avoids
the need for the driver to make that call.
