** [tickets:#1572] smf: Node by node upgrade**

**Status:** fixed
**Milestone:** future

The puropse of this ticket is to decrease campaign execution time, without 
rewriting the campaign.

If configured, smfd will automatically upgrade the nodes one by one in a 
rolling manner, with actions fetched from all rolling procedures in the 
campaign.xml.

This will prevent the campaigns different procedures to roll over one and the 
same node/nodes several times i.e. a node will never be 
locked/unlocked/rebooted more than once.

The procedures are not allowed to have order dependencies to each other.

Single step procedures are leaved "as is" and executed before the new "node by 
node" procedure.

This is the second step in a three step upgrade time improvement plan.
1) One step upgrade. Delivered with ticket #1401 in OpenSAF 4.7
2) Node by node upgrade. This ticket.
3) TBD, Upgrade several nodes at a time in a rolling manner
