Please unblock package nova

This upload fixes CVE-2017-7214, and bumps openstack-pkg-tools build-depends
to >= 54~, to make sure the nova-api config script doesn't use /sbin/route
and /bin/ip if they aren't available (as they aren't essential packages).

Please unblock nova/14.0.0-4,
Cheers,

+Description: CVE-2017-7214: do not include context to exception notification
+ The wrap_exception decorator optionally emited a notification.
+ Based on the code comments the original intention was not to include the
+ context to that notification due to security reasons. However the
+ implementation did included the context to the payload of the legacy
+ notification.
+ .
+ Recently we saw circural reference errors during the payload serialization
+ of this notification. Based on the logs the only complex data structure
+ that could cause circural reference is the context. So this patch
+ removes the context from the legacy exception notification.
+ .
+ The versioned exception notification is not affected as it does not
+ contain the args of the decorated function.
