pulse: rework sync

Browse source 
Use a global sync that both syncs the globals and completes the
operations.

In the case of a card profile change, first the nodes are removed
and added and then the Profile and Route info updated. We need to
be able to bind to the new node and get the device.profile.id
before we can find the active port of the node.

See #279
