[#249] pkg/netmap: Add CBF field in placement context

Browse source 
If CBF value is not set, then netmap package uses default CBF
value. However it modifies placement policy structure in
`GetContainerNodes()` because policy passed as a pointer.

Instead package can store CBF value in internal context and use
it without policy modification.
