Test live migration between hosts with differnet cpu_shared_sets

Browse Source 
This change modifes the nova-live-migration job to define
[compute]cpu_shared_set to different ranges on the controller
and compute node. in ci we have 8 cpus so the controller is set
to 0-5 and the compute uses 2-7

6 cores with our default allocation ratio should be sufficent
for our current level of concurrancy. This change also adds
the remaining cores as cpu_dedicated_set, they will currently
be unused but are thre if we want to enable pinned cpu testing
in the future.
