Pivot for container placement

[carpawell]

Why does netmap accept any pivot?

In practice a node always uses cid. So maybe it would be better to change the interface to accept cid to prevent incorrect usage.

It is really a feature, but I agree cid in the signature is more descriptive, especially, given that the function is called GetContainerNodes. Same can be done for GetPlacementVectors(oid).

Decided to accept typed parameters (oid.ID, cid.ID).

[roman-khimov]

Is there any way to GetContainerNodes(cid) and GetPlacementVectors(cid, oid)? These look OK for low-level things (with cid/oid), but I'd expect something easier to use from SDK.

This is the only method for now

neofs-sdk-go/netmap/netmap.go

Line 169 in ae44191

func (m NetMap) ContainerNodes(p PlacementPolicy, pivot []byte) ([][]NodeInfo, error) {

It'd be nice to have helpers for cid, oid.
